Need Help with Thread Dump

Below I have posted a thread dump of a thread I have no clue what it is doing. By blocking the lock <0x46fdf0b0> (a java.lang.Boolean) it is blocking my whole web application. It does not release the lock for at least 4 hours.

But what is the thread doing? I can't see any "waiting on" or "waiting to lock"...

Regards,

Andreas
