[mat-dev] NoSuchMethodError: org.eclipse.core.runtime.Status.<init>

["Brad Johnson" <9lt2qey02@xxxxxxxxxxxxxx>]

Hello Everyone,

I'm running Eclipse SDK version 3.2.2 included with Ubuntu 8.04. I installed MAT from the Update Site at: http://download.eclipse.org/technology/mat/0.7/update-site/ . It seemed to install okay and I restarted Eclipse and used File/Open to open a heap dump I had saved using jmap. It started to load the heap file and there was a progress bar. In a second or two it had advanced to about 25% and then in the window it said there had been an internal error. I looked in the .metadata/.log and found the following exception:

!ENTRY org.eclipse.core.jobs 4 2 2008-05-28 11:16:52.586
!MESSAGE An internal error occurred during: "Parsing heap dump from '/home/jjohnson/HeapDump.hprof'".

Any ideas?
