OutOfMemoryError after upgrade to OS X Mavericks

Hi everyone,
after the upgrade to Mavericks I am having a problem compiling my application:

Compiling 1 permutation
      Compiling permutation 0...
      [ERROR] OutOfMemoryError: Increase heap size or lower gwt.jjs.maxThreads

      [ERROR] Not all permutation were compiled , completed (0/1)

Before the upgrade all ran like a charme.
So I have done a bunch of tries, googling to find the right Java args, but without success. This is the latest extra args I used:

-Xmx8192m -XX:MaxPermSize=2048m -Dgwt.compiler.localWorkers=1 -XX:+UseCompressedOops -Dgwt.jjs.permutationWorkerFactory=com.google.gwt.dev.ThreadedPermutationWorkerFactory

Am I wrong something?
Thanks in advance for any help that could help me to solve this problem.

Eddy
