title: VisualVM unable to sampler memory
body: <p>I have a tomcat instance with the JMXRemote parameter configured. The local VisualVM is able to get a sampler on CPU, however, not for Memory. The memory button is grayed out with a summary saying: "Memory sampling: Not available. Cannot connect to target application. Make sure the application is running on a supported JDK 6 or JDK 7"</p>
  
  <p>JMXRemote parameter: </p>
  
  <pre><code>-Dcom.sun.management.jmxremote
  -Dcom.sun.management.jmxremote.port=9086
  -Dcom.sun.management.jmxremote.ssl=false
  -Dcom.sun.management.jmxremote.authenticate=false
  </code></pre>
