Thanks for the link! This seems to be a different one. Ours worked fine then it stopped forever until restarting Eclipse.

I traced it down to Takari Incremental build for Maven. Somehow M2E was loading this extension. It installs a SecurityManager into the JVM. This was causing a SecurityException deep down the stack for lacking permission to access the Equinox Log service.

I think the problem is that this exception was never surfaced anywhere - neither in the log nor on System.out/err.
