[kepler-users] Why doesn't "Listen to Actor" work on Kepler 2.2/2.3 for Windows?

Waiting sounds good.
It would be good if a few Kepler developers would switch over to Java
1.7, especially Windows.
Under Mac OS X, I downloaded Java 1.7 and updated ~/.bash_profile:
export
JAVA_HOME=/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
export PATH=${JAVA_HOME}/bin:${PATH}
export ANT_OPTS=-Xmx2048m
However, 'ant run' fails for me in the devel tree, even with 4g of
space. I get
[compile] The system is out of resources.
[compile] Consult the following stack trace for details.
[compile] java.lang.OutOfMemoryError: Java heap space
I don't have time to track this down today.
Under Mac OS X, Java 1.7 produces the following stacktrace when I start
up Ptolemy II:
This has been reported to Oracle, see
http://osdir.com/ml/macosx-port-development-java/2012-01/msg00201.html
and
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7130377
Unfortunately, I can't log in to the Oracle/sun bug site and vote on the
bug.
