This is a feature of the command console that Microsoft have provided, when text is selected in the command prompt window the process is supended until you unselect it by pressing a key. If you look when it is fozen the title bar probably contains the word SELECT.
The first option is to look at the properties for the command prompt and disable "QuickEdit Mode"
The second option is to install JBoss as a Windows service so that there is no command prompt window.
A third option is to redirect stdout and stderr to a disk file. The hangup usually occurs when the log attempts to write something to stdout but the console window is in selct mode.
that perfectly makes sense. Thank you very much.
