> 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.
