Summary: 2.1.5: memory leak

Initial Comment:
After a month troubles with 2.1.5 I've switched to 2.1.6 and then discovered that it is completely unusable on Linux. Ok, I've deinstall 2.1.6 but then discovered that there is no 2.1.5 on the CC update site in Eclipse. Ok, I've then decided to switch back to my old local patch of *1*.1.2 plugin for Eclipse 3.4.

And here is the fun: all last month with 2.1.5 plugin I've saw a very strange memory consumption of Eclipse: after start up 200-500 MB heap was already used (heap status monitor numbers) where it previously used 100-200. Now, after a rollback to the 1.1.2 version, the memory consumption failed back to 100 MB!!!

So it is definitely a memory leak somewhere in 2.1.* stream plugin. I guess too big caches etc.

Background: in my workspace I have ~120 projects accotiated with Clearcase, in average ~50-150 files (some of them 10 and some 900 files).

It would be nice to profile the plugin memory needs and where all the RAM goes into. Not that I do not have enough of it, but it is scary to think that just to start Eclipse (without doing anything else) I need 400 MB free RAM. At the end, other plugins also want to have some free memory to work, like FindBugs :-)

Regards,
Andrei
