Java Mission Control – Flight Recorder throws parser exception
<p>I'm trying to profile a Clojure app using JMC, but get the following exception when I try to start the flight recorder:</p>

<pre><code>java.lang.UnsupportedOperationException: This parser does not support specification "null" version "null"
</code></pre>

<p>JMC does let me start the MBean server, so I'm quite puzzled.</p>

<p>I've run JMC with the -consoleLog option, and got the following result when trying to start Flight Recorder:</p>

<p>I haven't found any mention of this issue in my searches and am a bit at a loss where to proceed with my investigation. Anyone has any suggestions?</p>

<p>Thanks!</p>
