Internal compiler error: Java heap space

[Julio]

Hi there,

We are developing a system using gwt 1.4 and netbeans 5.5.1. However, this bug start showing to us:

Copying 35 files to ...\build\web\WEB-INF\classes
Output will be written into ...\build\web\org.myhome.myfile
   Analyzing permutation #1
      [ERROR] Unexpected internal compiler error
java.lang.OutOfMemoryError: Java heap space
         [ERROR] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)
[ERROR] Build failed
...\nbproject\build-gwt.xml:13: Java returned: 1


I am researching about that and i found that I should increase my the amount of memory in the "netbeans.conf". But, this did not solve.

Can someone help me?

thanks.

Hi,

I don't really know netbean, but when I got this problem I just add -Xmx128M just after JAVA in my project-compile.cmd

Hope this help, unless sorry to disturb ! :)

I'm assuming you're using GWT4NB?

If so: under the "Files" tab, open up nbproject/gwt-build.xml. In the
"-post-compile" target change the

<java classpath="${javac.classpath}:${src.dir}" failonerror="true"
classname="com.google.gwt.dev.GWTCompiler" fork="true">

to something like

<java classpath="${javac.classpath}:${src.dir}" failonerror="true"
classname="com.google.gwt.dev.GWTCompiler" fork="true"
maxmemory="128M">

If you're not using GWT4NB (then you should probably think about it), then take
a look in the generated build.xml and find the <java> command that runs the
GWTCompiler, and follow the above ;)

Hope that helps a bit.

hello Jason,

your suggestion was very useful. The system came to work here.

thanks.

build-gwt.xml says:
"WARNING: Any manual modifications to this file may be automatically
overriden"

Is there a place where I can put the maxmemory directive so it will
show up in this file the next time I do a clean & build?

This is a known issue in gwt4nb. The workaround that jason
suggested is documented in the issue that tracks getting this fixed.
Sadly, no one has looked into an actual fix for the gwt4nb plugin.

See https://gwt4nb.dev.java.net/issues/show_bug.cgi?id=36

As a side note, Netbeans 5.5.1 has been superceded by Netbeans 6.0.1

Something like a GWT Compiler Max Memory field in the Project
Properties would be nice.
