Description

The JmxReporter should clear the mbeans map when closing. Otherwise, metrics may be incorrectly re-registered if the JmxReporter class is used after it is closed.

For example, calling JmxReporter#close followed by JmxReporter#unregister could result in some of the mbeans that were removed in the close operation being re-registered.
