A DESCRIPTION OF THE PROBLEM :
If THread.setName() has too long string value - for example 200charachters lenngth, Thread stack trace is not visible in Jconsolle Panel.

Note that if Jconsole were resized more than actual dusplay resolution and enougth to display whole Thread name , than Stack trace will be visible, but since Jconsole could be number of times wider than display width, this is more tnan "INCONVENIANT" no mater that it actualy not throws exceptions and application works.

NOTE! - addiionaly there are no suitable BUG report thread(topic) for JConsole in Sun bug report system.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Every thread must have its stacktrace info visible on screen no matter of Thread name length.
ACTUAL -
if thread name is longer(wider) than Jconsole window stacktrace is missing in visible aera.
