Compiling permutation hangs ?

Please some advice on the following:

When performing a GWT compilation (gwt 2.6.1), the compilation hangs.

How to solve this?

When running it in trace mode, I don't get any warnings and after about 4 hours (normally takes 4 minutes), I still see the console output below.

I played with the memory (Perm, Heap, Stack size), but no luck.  :(

I also commented all GWT RPC connections to backend, also no luck (I thought it get lost in some general generic usage).. :(

It does work in draft mode :)

I't strange as it's a gwt app that hasn't changed for some time, a part from some refactor actions that touched the app, and all of a sudden it hangs during the build (also when running the compilation manual through calling the maven plugin directly, command line).

I have another similar app, that is almost the same, has the same config, does compile well :(..

How to see why it's doing when it hangs? (I feel a bit blind, even when the "logLevel" is set to TRACE)

Tips how to solve this?

The GWT plugin arguments (even when removing/changing it, it has no effect):

----

<fragmentCount>8</fragmentCount>

<extraJvmArgs>-Xms1G -Xmx1G -Xss1024k -XX:PermSize=512m -XX:MaxPermSize=1024m -Dgwt.persistentunitcache=false</extraJvmArgs>

<localWorkers>3</localWorkers>

Console output:

----
