More Mac Woes

[Nicole Yankelovich]

Java Web Start stopped working for me this afternoon. Apparently I was not alone!

https://discussions.apple.com/message/21090162#21090162

Some time this afternoon, Apple updated a file called XProtect.meta.plist. The new version specifies a minimum version required for plugins. They changed this file in a stealth update to reference a version of Java Web Start that doesn't exist yet. This discussion includes a work-around:

https://discussions.apple.com/message/21090884#21090884

I've included the instructions that worked for me below. These are strictly for advanced users. Hope this helps others to avoid the panic I faced this afternoon :-)

Instructions for editing XProtect.meta.plist

Before you begin, make a backup copy of this file:
 /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist

In a terminal:
sudu vi /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist
password: [enter your computer's admin password]

The file will open in the vi editor. In the file, comment out the two areas as shown below. The comments start with "<!--" and end with "-->".

Yeow! Can you install something like nano so you don't have to have a
headbanging session using vi? Nano is crude enough, for console work
over a network, like vi, but is is more like dosedit and user friendly.

Since the Java mess, I have updated my Mac to Lion and downloaded the latest Java 7 from Oracle. After doing this, I am not able to successfully launch Wonderland.

After launching the JNLP, the Wonderland client window is displayed, but the window contents are gray. I do not reach the login screen. I am presented with the following error in the Java console. It appears that this is a bug with Oracle's Java 7 and OGL from the brief research I did. Thinking I will try to downgrade to Java 6.

Matt,

You don't need to downgrade. While Wonderland does not work on Java 7 on Macs at the moment, the Java 6 installation should still be on your computer. Try following the steps here as a work-around:

https://groups.google.com/d/msg/openwonderland/-ZU69XaSKC4/8rLpvu9MCXMJ

We have determined that the best way to fix this problem is to port Wonderland to the newest version of JOGL. An engineer has just started working on the process. I expect it will take several weeks before we have anything ready to test, but we're counting on everyone to help with testing, since this change will impact Wonderland on all platforms.

Let me know if that does the trick for you.

Nicole.

Thanks Nicole. I can launch OWL now.

It seems that Apple's Java support is atrocious and getting worse.

I have a couple of things on my mac that won't run on Java 7 yet, minecraft/tekkit launcher among them.  In case you launch things from command line, I have 2 scripts I use that set me up for 6 vs. 7:

% source ~/.bashrc_Java6

JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

java version "1.6.0_37"

Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)

Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

java version

java full version "1.6.0_37-b06-434"

java full version

% cat ~/.bashrc_Java6

# Java Standard Edition Software Development Kit

export JAVA_VERSION=6

export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

export PATH=$JAVA_HOME/bin:$PATH

echo JAVA_HOME=$JAVA_HOME

echo java version `java -version`

echo java full version `java -fullversion`

% source ~/.bashrc_Java7

java version "1.7.0_15"

Java(TM) SE Runtime Environment (build 1.7.0_15-b03)

Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

java version

java full version "1.7.0_15-b03"

java full version

% cat ~/.bashrc_Java7

# Java Standard Edition Software Development Kit

export JAVA_VERSION=7

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_15.jdk/Contents/Home

export PATH=$JAVA_HOME/bin:$PATH

echo java version `java -version`

echo java full version `java -fullversion`

I speak for neither Oracle nor Apple, but just myself.  I need Java working on my mac, though, regardless of who I speak for.  8^)

Hi!

I have changed the line

 <string>1.6.0_37-b06-435</string>

to

 <string>1.6.0_37-b06-434</string>

and now it works fine.

Regards.

José.
