Ok. It works if I add the following option to the command line ->
-L ../server/all/lib/gnu-regexp.jar
which adds the required library as an additional library. This tells me
that there is a bug in the way the Classpath is being loaded. If
gnu-regexp library is required for javax.management implementation
classes then it should be added to the classpath by default. Or am I
missing something?
