Hi Andrew,
how did you install the dtfj update site? Via the “classic”
update manager? Or did you unzip the site into the MAT directory? The latter
could explain this error. Also: the RCP is now bundled with Eclipse 3.5 (I believe
RC4 of the platform).
Andreas.

Subject: RE: [mat-dev] Latest builds
I've tried the
latest build MemoryAnalyzer-Incubation-0.8.0.20090615-win32.win32.x86.zip
and got the
following error after installing the DTFJ dtfj-updatesite.zip available from
IBM developerWorks.
The error went
away when I restarted MAT with MemoryAnalyzer -clean
I don't know
what caused the problem.
