Jerry Cwiklik closed UIMA-1749.
-------------------------------

       Resolution: Fixed
    Fix Version/s: 2.3AS

Added a cache object to create and cache an instance of a Serializer object for each thread processing remote CASes. The Serializer instance is cached using a thread id. This effectively dedicates a unique instance of Serializer to each thread processing a CAS allowing concurrency during serialization and deserialization of CASes.

> There is a single instance of a Deserializer object processing incoming CASes and also a single instance of a Serializer object processing outgoing CASes. This may bottleneck UIMA AS Service when handling large CASes and multiple threads are processing incoming and outgoing CASes. It would be more efficient to create and dedicate an instance of a Serializer/Deserializer to each processing thread so that multiple CASes cas be serialized/deserialized at the same time.
