Export this PMF to remote clients using pmfServer. Note that init
and start are not called on the added pmfServer. Only its close
method is called when the PMF is closed.
Get the bytecode for the hypedrive classes or null if hyperdrive is
not in use. The map maps class name -> byte[] or null if the class was
not generated at runtime (i.e. loaded from our classloader). Each byte[]
is compressed with gzip to save memory.
