Subject Threads blocked in Unsafe.park
Date Mon, 04 Jun 2012 13:27:02 GMT

I want the following problem:

While using OpenJPA with <property name="openjpa.Multithreaded"
value="true"/> i found myself having some threads waiting in "Unsafe.park"
state (see picture below). The blocking appears to happend on commit.

I'm using an EntityManager which does not allow any transaction.begin()
between a transaction.begin() & transaction.commit(). Also there is no
exception thrown.
