Could you please get GC logs with both versions and send them to us? Please use -Xloggc:filename.vgc and -XX:+PrintGCDetails.

So next probable step is do some profiling to see what's happening with memory. Are we allocating something in the implementation that didn't happen before ?? Thanks, Phil. The application has not changed. The big change is that the Java 7 VM is bundled inside the Mac app now. Previously, OSX was able to find an Apple-supplied VM under /Library.

Thanks, -Rick
