Wlwbuild task doesn't support jrockit

Question

In an attempt to speed up our build, we have tried out using the JRockit JVM for
ant. However, we were foiled by the wlwbuild task - it insists on invoking java
with the argument -XX:-UseThreadPriorities, which is not supported by JRockit.
We get:
[wlwBuild] Unknown option or illegal argument: -XX:-UseThreadPriorities.
[wlwBuild] Could not create the Java virtual machine.
[wlwBuild] Please check for incorrect spelling or review documentation of start
up options.
BUILD FAILED

Any suggestions would be most welcome. Should we try to override the ant java
task to ignore the option? Or is there a simpler fix?

Dude!
Try this.
change that target I was talkin about to
<target name="admin_command_common">
     <property file="${j2ee.home}/j2eetutorial14/examples/common/admin-password.txt"/>
<echo message="Doing admin task ${admin.command} with password"/>
<sun-appserv-admin
command="${admin.command}"
user="${admin.user}"
password="${AS_ADMIN_PASSWORD}"
host="${admin.host}"
port="${admin.port}"
/>
</target>
Reason?
well, the blinkin 'asinstalldir' attrib is ... optional!
The build succeeds and deploys the war.
C:\java\Sun\Appserver\j2eetutorial14\examples\web\bookstore1>asant deploy-war
