 Hi,
 
 VisualVM can only show the thread info if JMX is enabled. See
 
 http://visualvm.java.net/threads.html
 
 and
 
 http://docs.oracle.com/javase/7/docs/technotes/guides/management/agent.html
 
 for more info.
 
 Eclipse doesn't enable JMX by default, but with 
 
 env _JAVA_OPTIONS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=7199 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false" eclipse-devel
 
 you will see the thread info. See http://pasteboard.co/AeJjm3f.png
 
 FWIW, the new version of visualvm doesn't show the threads tab at all if the
 info isn't available.
