Error description

The wsejbdeploy ant task shows no support for  <jvmargs>:

It is necessary to be able to pass in a jvmarg for unique
problem scenarios, just as it is possible in the editable
command line ejbdeploy.{bat|sh} scripts.
There is no way to pass in jvmargs into wsejbdeploy similar to
system properties

For example:

<ejbDeploy
inputJar="${working.compile.dir}/${type}/${module.name}.input.ja
r"
wasHome="${was.home}"

workingDirectory="${working.compile.dir}/${type}/${module.name}"

outputJar="${working.archive.dir}/${type}/${module.name}.jar"
classpathref="compile.class.path"
codegen="${ejbdeploy.codegen}"
dbvendor="${ejbdeploy.dbvendor}"
keepGenerated="${ejbdeploy.keep.generated}"
quiet="${ejbdeploy.quiet}"
noValidate="${ejbdeploy.no.validate}"
failonerror="true"
trace="${ejbdeploy.trace}"
jvmMaxMemory="${ejbdeploy.jvm.max.memory}">

<systemProperty value="osgi.clean=true"/>
<jvmarg value="-XX:DoEscapeAnalysis"/>            <<< -XX
or -D Not Supported

</ejbDeploy>


Problem scenario ...

A JVM Crash occurs in the wsejbdeploy ant task. After
analyzing the crash dumps, JVM support determined this may
well be an instance of Sunbug 7026700:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7026700

(This is the strongest competitor of a few options.)
There is a Java 6  Hotspot v21 fix -
except its not delivered in the released Java 6 stream (Sunbug
2209127).
This is typical when there is an established workaround also
available:

The workaround is to pass in:

1) -XX:DoEscapeAnalysis
2) -XX:+ReduceFieldZeroing
3)
-XX:CompileCommand=exclude,org/eclipse/jst/j2ee/model/internal/
validation/ValidationRuleUtility,getMethod


It is necessary to use jvmargs, since a .hotspotrc file can no
longer be used in a JDK 1.6 JVM
This just for WebSphere Application Server.
It is not anything to be fixed in RAD.

Being able to pass in a jvmarg, just like for ejbdeploy.{bat|sh}
is essential for any useable wsant task like wsejbdeploy in
production environments.

Local fix

There is no known workaround at this time when using an ant
build script.

* RECOMMENDATION:                                              *
****************************************************************
When running the wsejbdeploy ant task a JVM Crash occurs. In
order to avoid such a crash, the following jvmargs have to be
passed to the jvm: -XX:DoEscapeAnalysis, -
XX:+ReduceFieldZeroing
,-
XX:CompileCommand=exclude,org/eclipse/jst/j2ee/model/internal/
validation/ValidationRuleUtility,getMethod, but the
wsejbdeploy ant task does not support the passing of arguments
to the jvm. So in order to apply the workaround the
wsejbdeploy ant task needs to be enhanced to support the
passing of jvm args.

Problem conclusion

Enhanced the passing of arguments to the wsejbdeploy ant
task in order to be able to apply the workaround for
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7026700.
The fix for this APAR is currently targeted for
inclusion in fix pack 8.5.5.2.  Please refer to the
