Error shown after upgrading to v1.6.0 (from v1.5.4)
I use Ant to (among other things) run a couple of programs that run
perpetually but have no
shutdown method. In Ant v1.5.4 I could use Ctrl-C to shutdown these
programs. I can do the
same thing with v1.6.0 but I always get the following error. Is there
any way to suppress this
error (and this error only) so that other users of my programs don't
think something abnormal
is happening?

Re: Error shown after upgrading to v1.6.0 (from v1.5.4)
Posted by Peter Reilly <pe...@corvil.com>.
I can confirm this error.
Can you enter a bugzilla report for it please?
The class:
public class NoFin {
public static void main(String[] args) throws Exception {
while (true) {
Thread.sleep(1000);
}
}
}
With a build script:
<project default="nofin">
<target name="nofin">
<javac srcdir=".">
<include name="NoFin.java"/>
</javac>
<java fork="yes" classname="NoFin"
classpath="."/>
</target>
</project>
Gives the error you have seen.
The code change in ant was in ProcessDestroyer.java revision 1.6:
Only register ProcessDestroyer when needed (and unregister it when no
longer needed).
