I did some debugging. It turned out that ANT <java> tasks will be run with
Java2 security enabled if the fork attribute is set to false (by default).
The key issue here is that the sample doesn't exit at the end. Even we grant
the java2 security permissions, it can only take to the point that the
sample hangs. If the folk=true, then the ANT task will hang as the
subprocess never exits.
We need to find out why the sample hang.
Thanks,
Raymond

Subject: Re: impl-bpel shutdown issue
I can't seem to find a good solution for this issue; that happens only
when running from an ant script. Looks like, when we try to shutdown
the thread pool executor in the destroy method of
ThreadPoolWorkManager, there is a security check and the
RuntimePermission to modifyThread is not set, thus the stack trace we
are seeing.
For some reason, trying to set the java.security.AllPermission in the
ant java task started causing classpath issues [1]
The only way I was able to make things work better was to change the
code in ThreadPoolWorkManager destroy method like below, but I guess
this might give us other side effects...
@Destroy
public void destroy() {
AccessController.doPrivileged(new PrivilegedAction() {
public Object run() {
try {
executor.shutdown();
} catch(Exception ex) {
//ignore
}
return null;
}
});
}
Any ideas would be appreciated...
