Problem with forked java process
I am trying to run a few java processes in forked JVM's. The following is where I try to execute the process:
<echo message="Starting testbed node1" />
<java fork="true" classpath="${sl.classpath}"
jvmargs="-Dsl.typename=testbed -Dsl.instancename=node1 -Dsl.cluster.directory=/sensorlogic/slbehavior/clusters"
classname="com.sensorlogic.behavior.tools.LaunchContainer">
<classpath refid="sl.classpath"/>
</java>
It starts to execute this process, beause I see some output from it, but it hangs and when I press control-C, I get the following
stack trace:
[java] java.lang.reflect.InvocationTargetException

Any input as to how I might troubleshoot this would be greatly appreciated. I can find now javadocs on java.lang.Shutdown. I am
running ant 1.6.

Is there any workaround for this? I also seem to get it from a spawned class that calls System.exit() and it really is a problem
because the JVM does not exit.
