Operation

To see a list of running Java processes on the system, and their process ids, enter:

liverepl

To see the available ClassLoaders for a specific process, enter:

liverepl <pid>

  -- where the pid is the process id for the process, obtained in
     the step above.

To connect a repl to the process, enter:

liverepl <pid> <classloader-id>

  -- where the pid is the process id for the process.
  -- and the classloader-id was obtained in the step above.

if you aren't sure which ClassLoader to use, try '0', which will always be the System ClassLoader.
