If you have a variable in Windows Environment Variables called _JAVA_OPTIONS, just delete it and it should fix the issue, else.

If you have Razer Synapse installed, usually comes with any Razer products it will attach an invisible Environment variable of _JAVA_OPTIONS: -Xmx 512M.

Currently as Razer are still working on a patch to fix the bug (Work on fix confirmed by Razer 23/12/2014) you have a few options which are all pretty ugly.

1. Set your own _JAVA_OPTIONS variable:
Navigate to your Environment Variables window
click New... name: _JAVA_OPTIONS, value: (designate your Xmx and Xms values here) e.g. -Xmx1G -Xms1G

Xms is your starting heap size, Xmx is your maximum heap size. Debates rage on about what to do with these, just try a few settings and see what works best for you.

2. You can write a batch file to set a system/user variable and run minecraft.
Check out this if you're interested in batch files

Or use this:

Replace Xmx and Xms values with your desired allocations and save the .bat file to where you are running the server from.

to use this with single player change the line java -jar server.jar to:
java -jar Minecraft.exe
then put the batch file in the same place as Minecraft.exe (the normal launcher with the cube icon)

It's possible you may have to fiddle around with the setx command to make permanent changes to environment variables but the above batch file should work by overriding the _JAVA_OPTIONS variable for the duration of the CMD session

-us/library/cc755104.aspx for information on SETX

3. You can uninstall Razer synapse (this option sucks but yeah).

Warning!!, setting your own environment variable for _JAVA_OPTIONS: will set those options to any java application that you run as such you may want to delete the variable after you finish playing.

I have no clue why I can only get Liquibase version 3.5.5 and 3.6.3 to work form my command prompt. I have tried a bunch of other versions like 3.8.9, 4.3.3, 4.4.0, and 4.4.2 and all have the same problem.

Did you figure this out? Looks like there may be some other java environment variables that are messing with the output, for instance, I see _JAVA_OPTIONS is being picked up. You might clear some of those other options if you have not already resolved this issue.

I just tried to get this working again. I am still having the issue after using the windows installer to install version 4.11.0 of Liquibase and have a recent version of Java 11 JDK setup as my JAVA_HOME system variable.

Now everything is working fine and as expected. I can even switch between different versions of liquibase again like I was able to on my previous laptop when I was able to switch between the 3.X.X versions of liquibase before the 4.X.X series was release.

Oracle supports Oracle REST Data Services (ORDS) running in standalone mode using the built-in Jetty web server, so there is no need to worry about installing Tomcat or WebLogic unless you have a compelling reason to do so. Removing this extra layer means one less layer to learn and one less layer to patch.

The ORDS installation process is similar regardless of the application server being used, so you should follow the installation described hereWe will use the following environment variables when referencing the paths in this article. Notice we are adding the ORDS_HOME/bin directory to our PATH, so we don't have to explicitly state the path each time we use the ords command.

By default ORDS uses HTTP on port 8080. We can alter the port using the --port argument. We can make ORDS use HTTPS by adding the --secure argument, which will default the port to 8443, but we can alter that using the --port argument. In this example we explicitly set the port to the default HTTPS value.

ORDS will automatically create a self-signed certificate for use with SSL if you don't specify a valid certificate and key. The certificate and key are stored in the "$ORDS_CONFIG/global/standalone" directory. Resources will now be available from the following URL, adjusting your hostname as applicable.

You should probably be fronting ORDS with a reverse proxy or a load balancer, which is where your Certificate Authority (CA) certificates should live. Even so, you will probably want your internal traffic to use HTTPS also, so you will need to configure Jetty to use HTTPS. If you have a proper CA certificate and key, make sure they are in DER format. In this case we will manually create a new self-signed certificate and use that for the HTTPS configuration. Remember to adjust the "dname" and passwords as required.

ORDS will automatically handle the typical HTTP errors. If you are fronting ORDS with a load balancer, you may wish to use that to handle custom error messages, rather than altering the ORDS configuration. If you need it, ORDS can handle custom error pages. Amend the error.externalPath setting with the location of your custom error pages.

This document describes several unsupported properties that youcan use to customize how the 2D painting system operates. You mightuse these properties to improve performance, fix incorrectrendering, or avoid system crashes under certain configurations.For example, on a small set of Microsoft Windows computers with badDirectDraw or Direct3D drivers, the use of hardware-acceleratedrendering might cause system crashes. You can use properties tospecify that on these computers, the Java 2D system shouldn't useDirectDraw or Direct3D.

2D properties have the prefix sun.java2d.. Tospecify them, you can use either command-line flags or the_JAVA_OPTIONS environment variable. For example, youcan specify the 2D trace property with a flag whenrunning an application, like this:

Some system properties are also settable using environmentvariables. For example, the d3d property has theequivalent environment variable J2D_D3D. The propertydescription lists the equivalent environment variable, if oneexists.

An OpenGL-based pipeline for Java 2D was introduced in 1.5 Beta1 for Solaris/Linux and 1.5 Beta 2 for Microsoft Windows platforms.This pipeline is currently disabled by default. It provideshardware acceleration for simple rendering operations (text,images, lines, and filled primitives) as well as those that involvecomplex transforms, paints, composites, and clips.

The methodname represents the basic graphicsoperation that is used to do the actual rendering work of aGraphics method invocation. These method names willnot necessarily map directly to methods on theGraphics object, nor will the number of calls made onthe Graphics object map directly to the number ofprimitive operations performed.

The composite names match the names in theAlphaComposite class fairly closely with the suffix"NoEa" meaning that theAlphaComposite instance had an "extra alpha"attribute of 1.0. The "SrcNoEa" type is the most commonlyused composite type and represents the simplest way of transferringpixels with no blending required. "SrcNoEa" is often usedbehind the scenes even though the default composite is"SrcOver" when opaque colors and images are renderedbecause the two operations are indistinguishable for opaque sourcepixels.

Platform rendering pipelines are sometimes used for doing opaqueoperations on surfaces accessible by a platform renderer, such asX11, GDI, or DirectDraw. Their names currently use a simplifiednaming format, which has a prefix for the platform renderer and thename of the operation but without any classname or operand typelist. Examples are "X11DrawLine","GDIFillOval", and "DXFillRect". In the futurethese names should more closely approximate the names of the otherprimitives.

What the flag really does is override what the JRE reads fromthe user's desktop settings as the user's desktop antialiased textpreferences. Swing instructs Java 2D to render Swing text to matchthat preference, so by overriding it you can control Swing text.This applies to standard Swing components (like JTextArea, JButton)in the Metal L&F (aka Java L&F) and native (Windows, GTK)Swing L&Fs. It should also apply to any custom component orL&F which picks up the same property.

This property can be used to eliminate the initial delay inrendering when the images are being copied to the VRAM after thefirst few copies. Instead, the delay is effectively shifted to theimage creation time.

This could be useful behavior when you know that yourapplication will be able to take advantage of image management;just get the overhead of the copy over with at the start instead ofincurring some number of slower copies to begin with and thenhaving the copy overhead at some later time.

When this property is set to 16, it forces the acceleratedsurfaces for managed images (created withGraphicsConfiguration.createCompatibleImage(w,h,TRANSLUCENT)) or translucent images loaded withToolkit.getImage to be in 4444 format. The systemmemory surface for these images will be in 4444 format as well.

This option is also useful for computers with video boards (suchas 3dfx Voodoo3) that don't support 32-bit textures. When the Java2D system uses 32-bit textures, as it does by default, then when itencounters a card without 32-bit texture support it disablessupport for accelerated translucent images. If you wantacceleration of translucent images on a video board that doesn'tsupport 32-bit textures, set the d3dtexbpp property to16.

Obsoleted in: Java SE 6 Update 10
Intended use: To turn on hardware-accelerated scaling whenthe DirectDraw/Direct3D pipeline is in use.
Introduced: 1.2
Default value: false
How to use: Setting this flag to true enableshardware-accelerated scaling if the DirectDraw/Direct3D pipeline isin use. DirectDraw/Direct3D hardware scaling is disabled by defaultto avoid rendering artifacts in existing applications. Theserendering artifacts are caused by possible inconsistencies betweenthe scale method that the software scaling operation uses (nearestneighbor) and the different scale methods that video cards use.Certain events that occur while an application is running mightcause a scaled image to be rendered partially with hardware scalingoperations and partially with software scaling operations,resulting in an inconsistent appearance. For now, you can enableacceleration by setting the ddscale flag to true.
