Allocate interrupted exception before re-acquiring lock

Allocating the monitor exception after acquiring the lock can cause
a deadlock in the following scenario:

Reference queue daemon interrupted from wait() on
ReferenceQueue.class. Tries to allocate exception and starts a GC
that blocks on WaitForGcToComplete.

Some other thread is already doing a GC, and tries to enqueue the
cleared refereneces. This deadlocks trying to lock Reference.class
in ReferenceQueue.add.
