Examples of JpaPersistenceContextManager

org.drools.persistence.jpa.JpaPersistenceContextManager
This class manages {@link JpaPersistenceContext} objects, and the underlying persistence context ({@link EntityManager}) instances for a persistent {@link KieSession} and other infrastructure classes that use persistence in KIE projects.
(For reference in the following documentation: the {@link EntityManager} is the class used to represent a persistence context)
There are 2 issues to take into account when looking at or modifying the code here:
1. One of the features made available here is the ability for the user to supply their own (Command Scoped) persistence context for use by the {@link KieSession}
2. However, significant race-conditions arise when a Command Scoped persistence context is used in one persistent {@link KieSession} by multiple threads. In other words, when multiple threads call operations on a Singleton persistent {@link KieSession}.
This class uses {@link ThreadLocal} instances for two things:
1. The internal Command Scoped {@link EntityManager} instance.
