    Description

      When using JConsole to change the MaximumThreads from default 32 to 128 for ReadStage and MutationStage this exception is displayed 'java.lang.UnsupportedOperationException'. Nothing is written to the system.log.

      If I perform the same change using Apache Cassandra 2.0.8.39 I can change MaximumThreads to 128 for ReadStage and MutationStage without any problems. See the attached image showing the two machines.
