Stacktraces while parsing heap [message #646174]

While parsing a heap dump, using a freshly downloaded version of MemoryAnalyzer, I suddenly get a couple of stacktraces, after which parsers stop. What is going on here? Are the indeces generated so far usable?

Regards,

Guus

Hi,

the problem was already reported and fixed.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=331686
If you need the fix now, you can try updating your MAT to the latest snapshot version:
http://www.eclipse.org/mat/snapshotBuilds.php, i.e. this one:
http://download.eclipse.org/mat/1.1/snapshots/20101215/updat e-site/

Let me know if this helps.

Hi Krum,

I'm having the same problem here with the Linux x64 version (the version is probably not relevant, but anyway).
Is there any snapshot build of the standalone MAT? Or is it possible to build it from the plugin one? Or do you have any plans on releasing a new version this week? ^_^

Thanks,

Nicolas

Hi,

You can try to update your standalone installation. It should be possible to use the update manager - "Help" -> "Software Updates" -> "Find and install". You can then add the update site, or an archived update site and bring the MAT plugins to this version.
I think this should help. Let me know if you have further troubles.

The update worked just fine on my PC, but it doesn't really fix my loading issue... I'm pre-indexing the hprof file on a server with no X. (Actually, I don't even know if I would be able to load those indexes afterwards.)

Thanks anyway for the quick reply!

Well, there are currently no standalone versions for download which could help you, and I think we're not publishing any in the next couple of weeks.
I know this isn't a best practice, but you can probably replace the org.eclipse.mat.* bundles under <mat>/plugins/ on the server with the new ones from your PC (they are not OS specific).

That would have been a fun solution to test! Finally, I've managed to open the dump, via remote desktop, with the standalone snapshot.

Awesome tool by the way!
