[jira] [Resolved] (HBASE-14707) NPE spew getting metrics via jmx

Mike Drob resolved HBASE-14707.

Resolution: Cannot Reproduce
Not seen in a while and not enough info to reproduce. The JVM used for the
original report seems to have stack trace optimization turned on, where it
discards the rest of the NPE after printing it the first few times. If this
comes up again, then we'll try to address it.
