JCreator Pro 2.5 Build 8 and Debugger facilities

[Guy Van Rinsveld]

I know JCreator PRO is a shareware and the Lite version is really the
freeware version.
The Lite version is very useful but doesn't get the debugger tool.
The problem is that I have seen this feature working on other computer but
cannot install it correctly.
Menu : Build / Start Debugger
I'm getting the following error :
Unrecognized option : -XDebug
Could not create The Java Virtual Machine
Fatal error
Target VM failed to initialize

Every other features are working (compile, run...)
An idea ?
Thanks
