We're experiencing problems with the server VM when building
J2SE. It is not easy to make a small reproducible test case,
but we can provide access to the failing workspace.

I'm not able to reproduce the problem on the client VM. Also,
if I use -J-Xint the problem goes away.

On machine nisse.sfbay in the directory /u/peter run:

If I don't use -Xbatch, the javac run will not fail every time.
Here is the output from a successful run:
