> If JAVA_HOME is incorrectly set in a user's environment when launching storm,   
> it fails with an error message that is confusing to end users.
> Traceback (most recent call last):
>   File "/home/y/bin/storm", line 485, in <module>
>     main()
>   File "/home/y/bin/storm", line 482, in main
>     (COMMANDS.get(COMMAND, unknown_command))(*ARGS)
>   File "/home/y/bin/storm", line 225, in listtopos
>     extrajars=[USER_CONF_DIR, STORM_DIR + "/bin"])
>   File "/home/y/bin/storm", line 153, in exec_storm_class
>     ] + jvmopts + [klass] + list(args)
>   File "/home/y/bin/storm", line 97, in confvalue
>     p = sub.Popen(command, stdout=sub.PIPE)
>   File "/usr/lib64/python2.6/subprocess.py", line 642, in __init__
>     errread, errwrite)
>   File "/usr/lib64/python2.6/subprocess.py", line 1234, in _execute_child
>     raise child_exception
> It would be nice if this were either detected and a proper error message printed, or if it warned and fell back to the java found in PATH.
