I downloaded the personal edition of JBuilder and I'm able to compile and run a program, but an error is generated every time I try to debug the program ("step into" or "Debug Project") When I select F7 to invoke the debugger, the activity monitor dialog is launched with a message that it is "Initializing the Java virtual machine", then the following error message is displayed:
Note the error occurs debugging welcome.jpx.  

Thank you very, much in advance for your help.
