The Free On-line Dictionary of Computing (30 December 2018):

Java Remote Method Protocol
JRMP

    (JRMP) A proprietary wire-level protocol designed
   by Sun Microsystems to transport Java RMI.

   JRMP serves the same function as IIOP, but also supports
   object passing.  Sun plans to offer IIOP as an alternative
   to JRMP.

   Sun do not appear to use this term any longer, simply
   referring to the "RMI transport protocol".
