I was looking for a nice tool to read java heap dumps and found that regular JHat was not a great way to go with the 1.6GiB dump files I have. A friend pointed me to a Eclipse project Memory Analyzer (MAT) http://www.eclipse.org/mat/ which is the old SAP analyzer…
Eclipse MemoryAnalyzer Exit Code=-1
Starting it up I got the Exit Code=-1 error and found that this tool is currently not working with java 1.6.x on a mac. If you want to force the tool to use 1.5 open a terminal window and follow these instructions:
freddy@svn:~/mat/MemoryAnalyzer.app/Contents$ vi Info.plist
Uncomment this line:
This will force the use of Java 1.5!
