murray waters commented on MGWT-118:
------------------------------------
This can be worked around by removing "-localWorkers 2" from the command line
above, and consequently by adding <localWorkers>1</localWorkers> to the
configuration of gwt-maven-plugin in your pom.
I'm now going to try and see if I can reproduce this without maven, and perhaps
file a bug to GWT again if this is the case.
Also perhaps in order to consider this plugin fixed localWorkers should be 1 by
default or maybe you need to detect an IBM JVM and set localWorkers to 1 if
this is the case?

> Originally reported as a possible GWT bug
> (http://code.google.com/p/google-web-toolkit/issues/detail?id=4031), but does
> not occur when running the webAppCreator tool from command-line to generate a
> simple example application and compiling it with 'ant build' from
> command-line.
> "_j2se_j9=71168" does not sound like a classname at all so it seems that
> gwt-maven is scooping that string up from elsewhere and trying to use it as a
> classpath resource.
