I’m running mac osx 10.6.2

I have java 6.0 32 bit selected in the java preferences utility.

This ant script runs fine when my project is using java 5 jre. when I switch to java 6 jre under libraries, it always ends up failing with this error:

If I switch back to java 5 jre it compiles fine. I’ve tried everything I can think of. any ideas?

Under external tools configuration, I have seperate JRE set to JVM 1.6.0 (MacOS X Default). Under the Environment Tab, I’ve added a Variable ANT_OPTS with Value -Xmx768m. That doesn’t fix the issue. I’ve tried modifying the eclipse ant.sh file to add memory variables under the ANT_OPTS variable there. That doesn’t fix the issue.

adamsrobw,
Try setting fork=true of javac tag in your ant script as suggested in the following link
http://lists.apple.com/archives/Java-dev/2007/Mar/msg00026.html

Let me know if that works.

That fixed the issue. Thanks so much. You’ve earned an Eclipse user for life.
