StateManagement EntityManager Creation
Patch 1: This change modifies StateManagement methods that use transactions so that an EntityManager is created each time the method is called. This eliminates issues with EntityManager transactions being shared across threads causing errors when multiple threads are active. Issue-ID: POLICY-518 Change-Id: I071660a530de610ec56af82347b92496f87bf4e1 Signed-off-by: Kevin McKiou <km097d@att.com>
