No, it does not sound like the same problem.  I am not aware of this bug.
My first inclination would be to blame Java Workshop, but there could be
some other problem.  Specifically, the class gnu.bytecode.SysInPort
is somewhat fragile.

None known.  However, it may be worth trying to replace:

  private static InPort systemInPort = new SysInPort (System.in, "<stdin>",
                                                      OutPort.outDefault());

in gnu/mapping/InPort.java with:

  private static InPort systemInPort = new TtyInPort (System.in, "<stdin>",
                                                      OutPort.outDefault());

That may cause problems with the GUI window, but should make the basic
stand-alone repl in a DOS prompt more robust.
