Hello,

I have seen that MAT is removing unreachable Objects from the Heap dump
while loading it initial. I wonder if any statistics on those are
available. We had some problems with GCs where a major collection was not
running for hours (good) but that also lead to a large number of not
finalized Objects. Looking at the dead objects in the Heap (at least a
histogramm) would be cool).

One option would be to just print a histogramm of the removed classes,
another would be to somehow make them more inspectable. Maybe create a
virual "finalizer queue" ...

Greetings
Bernd

Hi Bernd,

for now you have this option:
http://wiki.eclipse.org/index.php/MemoryAnalyzer/FAQ#MAT_Doe s_Not_Show_the_Complete_Heap

We will make more options available later. If you are interested, add
yourself to the CC of this bugzilla:

Hi guys,

I have some troubles in using eclipse-jee-europa-winter-win32.
The process eclipse.exe, not the process javaw.exe,
consumes all cpu resources when I open or close or save java files.
But there is nothing when I operate on the other types files.
And there is no virus in my PC, the other applications are also OK.
I am worrying about this. It makes me inefficient.
What can I do? Thanks a lot!

BTW, I tried somethings:
1. reinstall the eclipse
2. download eclipse from eclipse.org
3. use the other version

Hi Leslie,

I am not quite sure if we can help you here in this forum. We are
discussing the Memory Analyzer, a plug-in to Eclipse which looks at heap
memory. So maybe try one of the general purpose newsgroups.

Other than that, a thread dump of the Virtual Machine could indicate who
is doing something....

Andreas.
