Hi,
I've got a GWT project that I'm upgrading from 1.5.3. to 1.6.4 and
after adjusting my Ant build task as follows
<target name="compile-gwt" depends="compile" description="GWT compile
to JavaScript" unless="skip.gwt">
<java failonerror="true" fork="true"
classname="com.google.gwt.dev.Compiler">
<classpath>
<fileset dir="${src.dir}"/>
<fileset dir="${build.dir}"/>
<fileset dir="${gwt.home}">
<include name="*.jar" />
</fileset>
<fileset dir="${local.lib}/gwt-3rdparty">
<include name="*.jar" />
</fileset>
</classpath>
<!-- add jvmarg -Xss16M or similar if you see a
StackOverflowError
-->
<jvmarg value="-Xmx512M" />
<!-- Additional arguments like -style PRETTY or
-logLevel DEBUG -->
<arg value="com.vamosa.VamosaClient" />
</java>
</target>
When running the task it causes the following error, from both inside
Eclipse as well as on the command line;
BUILD FAILED

A quick google reveals other Java systems (like Confluence) running
into issues with the fork-flag, so I tried setting fork=false, but
that generated allsorts of classloading nastiness.
I'm running 64-bit Ubuntu 9.04. Any help would be greatly appreciated.
Many thanks,
