[news.eclipse.technology.memory-analyzer] Error during the parser

[ruppur@xxxxxxxxx (roger )]

Hi guys,
While I am trying to open one dump file, actually after the parser the 
following
error appears.
Do you have any similar experience regarding the issue?
"Extracting Biggest Objects" has encountered a problem.
Dominator tree now available. Delete indices and parse again.

I am using IBM JDK 1.4.2 SR12 and zipped dmp file.

Thank you guys.
Best Regards
Roger
