InstaDMG and Java

Is anyone else having issues getting Java to run with an InstaDMG build? I have two separate builds with all updates - but Java won't run on either one of them. I can't even launch Java Preferences - it just crashes. The logs show: dyld: Symbol not found: _kJVMInfoHomePathKey Referenced from: /Applications/Utilities/Java/Java Web Start.app/Contents/MacOS/Java Web Start Expected in: /System/Library/Frameworks/JavaVM.framework/Versions/A/JavaVM Exited abnormally: Trace/BPT trap Anyone else seeing this?
