Problems with Eclipse (and m2eclipse)

I use Eclipse and I have serious problems :-( First I try to reconstruct my situation rudely for you:

1. I installed Eclipse Java EE Helios and JDK 1.6.0_21 and configured windows' system vaariables
2. I installed m2eclipse
3. I generated an archetype for a JSF Webproject

I use Windows XP Professional SP3

So... now Eclipse has very big problems. When I try to open the pom.xml or use some maven specific options eclipse stops working and a permgen space error occures, like here in my last session:

I can't explain that to myself, there are a lot of reasons. Maybe somebody had simialar problems and can help me with that.

Update:

:-( After 30 minutes it startet leaking again :-(

It seems like Eclipse remains in an endless loop. The task 'Eclipse' uses ~50% of my CPU continously.

That's very strange. Here is my eclipse.ini:

-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-XX:MaxPermSize=256m
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms128m
-Xmx512m

Maybe there is a problem ?!? Does somebody has an Idea?

EDIT: I need to say that it's better. That problem occurs very rarely.

Update 2:

May Somebaody help me with configuring my eclips.ini please. So that I can work with JDK 6-21... Or mshould I maybe use an older version?

That's it so far:

-startup
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.0.v20100503
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-XX:PermSize=128M
-XX:MaxPermSize=256m
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms128m
-Xmx512m

Okay I followed shipmaster's recommend and posted another question: Trouble with Eclipse

Another option, that has worked for me, is to adding in Run->Debug configurations...->(Your Maven build)->JRE tab->VM arguments some VM arguments:

-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m -XX:NewSize=128m

Hope this help...

Updated:

Or even, you can add the same arguments to:

Window->Preferences->Java->Installed JREs->(Your preferred JDK or the JRE used by your Maven instance)->Default VM Arguments

You need to increase your max perm size by passing -XX:MaxPermSize=256m in eclipse.ini

Note: For Helios and your version of java, please use the above, using the other argument (launcher.XXMaxPermSize) will not work because of a bug.

See more in the following links: http://wiki.eclipse.org/FAQ_How_do_I_increase_the_permgen_size_available_to_Eclipse%3F

https://bugs.eclipse.org/bugs/show_bug.cgi?id=319514

I had a seem a similar issue with my eclipse galileo. It was working fine all this while with JDK 6 update 3, until I had updated my jdk 1.6.0_21.

When I changed my JDK path to point to Jdk 6 update 3, it started working fine.

Hope this help !!!

Thanks, Amit Chhajed
