> As a Streams developer, I should be able to run multiple Streams in a serial fashion
without issue. Currently, JMX beans (which are used for monitoring the Stream's activity)
are not cleared when a Stream is shutdown. If a new Stream is started afterwards (without
a JVM restart) then there is a collision in the naming of the JMX beans which causes an exception
which shuts down the subsequent Stream. Need to build in functionality to clear all JMX beans
on shutdown.
