PM70609: CCRC Plugin does not properly share state and can lead to inconsistencies on startup

APAR status

• Closed as program error.

Error description

• During startup Eclipse may create multiple instances of the same
  plugin. In these scenarios, if state is not properly shared (for
  example: each instance does not carry the exact same state),
  problems will occur during startup.
  
  We are seeing some NullPointerExceptions and
  ArrayIndexOutOfBounds that are directly related to this issue
