Fwd: OOME PermGen space

[Zsolt Kúti]

Hello,

We have a maven build that keeps failing on Jenkins (1.580.2), but runs fine outside of it.
Other versions of the same project have no problem, all runs with the same general
Maven setting.
This build shows various errors on repeated runs, the common part in them is PermGen.
We tried to tune Maven settings by increasing MaxPermSize, adding -T 2 to no avail.

Stacktrace below was produced after a Jenkins restart.

Any idea what's going wrong here and how to overcome this?

Thanks!

Zsolt

There is no tuning of the permenant generation in the above command.

additionally if you are forking javac (which is normally the way to go, and I don;t think you are from the above stack trace) you may need to tune to fork parameters.
