JConsole is stuck forever in "Connecting to ..." window when trying to connect to URL with unexisting host and too big port number:

$ jconsole service:jmx:rmi:///jndi/rmi://zoloto.partii:128000/jmxrmi

An exception is printed in console:
Exception in thread "VMPanel.connect" java.lang.IllegalArgumentException: port out of range:128000
