Analysing JAVA core dump file

[websphere]

Does anybody know which editor is useful to analyse Java core dump file generated when a server crashes.WSAD generates the j9.dmp file.It is a memory dump.I have tried it with hexadecimal editor without any use.I dont know how to further investigate the things as given in the red book for was 6.0 server crash problems.

The Dump Diagnostic for Java Tech Preview is a nice tool, although it
has considerable system requirements if I remember:

4GB Disk
1.5 GB Mem

I know it works with heapdump files, but not sure about javacore files.
Here is another alternative:
