> In *JMXJsonServlet.java* file, when invokes *MBeanServer.getAttribute()* method, many
catch clauses followed, and each of them contains a log statement, most of them set the logging
level to *ERROR*. However, when catches *RuntimeErrorException* in line 348 (r1839798), the
logging level of log statement in this catch clause is *DEBUG*, the annotation indicates that
an unexpected failure occured in getAttribute method before, so I think the logging level
shuold be *ERROR* level too.
