Subject [jira] [Created] (UIMA-5146) Multiple pipelines need to share just the resources in a ResourceManager

Burn Lewis created UIMA-5146:
--------------------------------

             Summary: Multiple pipelines need to share just the resources in a ResourceManager
                 Key: UIMA-5146
                 URL: https://issues.apache.org/jira/browse/UIMA-5146
             Project: UIMA
          Issue Type: Improvement
          Components: Core Java Framework
            Reporter: Burn Lewis
            Priority: Minor
             Fix For: 2.9.0SDK


If an annotator creates an AE to run an independent pipeline with a different typesystem it
can't reuse the RM as the CasManager's merged typesystem cannot be updated.  We should be
able to create a child RM that shares the resources (delegates to the parent?) but has a unique
CasManager.  The 5-arg RM constructor used for pears can be used but it requires access to
maps that are protected in the existing RM.  Perhaps we could add:a method such as: 
ResourceManager createChild();
Destoying a child RM should not affect the parent and vice-versa.
