Not a bug, exactly

Posted by Scott Bain on February 12, 2002 at 5:51 PM

This is not really a bug. The java System property java.class.path is used to build a linked link when the JRE is instantiated, then is not re-read. Therefore, changes you make to the property don't really do anything to the existing virtual machine.
