Description

The EntityCache used by the FST Linking engine is not correctly managing the reference count. This can prevent instances to be immediately destroyed when they are no longer used. They will still get destroyed by the GC, but only at a later point in time causing higher memory consumption as needed.

In addition EntityCacheManager needs a close() method allowing to explicitly close the cache if the Engine is deactivated.
