I am using flex builder 3 plugin on top of wtp eclipse 3.2.2. The application is quite heavy and needs 2 GB of physical RAM when running on JBoss.
I have eclipse.ini set with the following options:
Now whenever I am trying to build the project, eclipse crashes with the following error:
# An unexpected error has been detected by Java Runtime Environment:

After looking at this log, I got the line starting with "compacting perm gen" which made me thinking that there might be some problem in Perm Gen memory. I got quite a few references on the net but none could lead me to concrete solution. I tried with different combination of settings for MaxPermSize but no luck.
has anyone faced this problem on eclipse and aware of any possible solution?

What you experienced was a crash of the JVM - something that shouldn't happen, even in low memory situations. Make sure you file a bug report with Sun as the message suggests.
Also, it is not unusual to see the permgen space 99% occupied. The JVM usually uses only as much permgen space as is required. Note, for example, that you set max permgen size to 300MB but the JVM is using only 38MB.
I noticed that you are using JDK 1.6.0_03. That is a really old JVM. I very highly recommend upgrading to the latest JDK 6! I know, for example, that JVMs older than 1.6.0_04 have issues with JBoss AS 5.0.0.GA, and have serious issues when running on Vista.
Actually I am already using JVM 1.6.0_11-b03. And currently the problem is while running eclipse and could not reach to deployment stage at all so far. One thing I noticed is that I enabled some code styles in the eclipse preferences, and since then I am facing this problem. But now even after reverting those changes, the problem persists.
I have already reported this potential bug to sun and waiting for their response.
