      Description

      In large UIMA deployments with multiple threads, some synchronization contention is detected in RsFullFeatNames and RsLang, and the caching that occurs with MetaDataObject_impl. Replace with concurrentHashMap, and for RsFullFeatNames - discard the weakpointers to keys, which is not much of a hazard - because the tables are relatively small vs other memory uses.
