If you can run (and reproduce the issue) on Java 6, you can test it on the
Threads page of "jconsole".

Or use "jstack":

jstack -help
    jstack [-l] <pid>
        (to connect to running process)
    jstack -F [-m] [-l] <pid>
        (to connect to a hung process)
    jstack [-m] [-l] <executable> <core>
        (to connect to a core file)
    jstack [-m] [-l] [server_id@]<remote server IP or hostname>
        (to connect to a remote debug server)

    -F  to force a thread dump. Use when jstack <pid> does not respond
(process is hung)
    -m  to print both java and native frames (mixed mode)
    -l  long listing. Prints additional information about locks
    -h or -help to print this help message
