Remote debugging on Windows XP fails when using port 5000

Abstract: Remote debugging on Windows XP fails when using port 5000

Question:

When I attempt to initiate remote debugging on Windows XP, JBuilder appears to freeze. Why is this occurring?

Answer:

If you are running Windows XP, do not use 5000 as the port number/address through which the debugger communicates with a remote computer. Windows XP reserves this port for the Universal Plug & Play. This is also documented in the release notes for JBuilder 8, 9.
