--------------------------------------
Hi [~chesnay],
Could you share the command for launching the JVM process when you run into
this issue?
It is by design that cpu cores is always specified before launching the JVM
process, as a '-D' argument. One thing I can think can think of is that, there
might be some other unrecognized token in the command, that prevents parsing of
the following arguments.
