It seems encon doesn't survive while decoding->encoding+serializing PIDs in format of #PID<0.639.0>


io.appulse.encon.terms.exception.IllegalErlangTermTypeException: Class io.appulse.encon.ter
ms.type.ErlangAtom doesn't fit to term type ATOM

Steps to reproduce:

  1. In Elixir: File.write!("pid.term", :erlang.term_to_binary(self))
  2. On Java side:
    Read the first byte of "pid.term" file (it's 131)
  3. Read the rest into ByteBuf
  4. Decode bytebuf into proper java class with ErlangTerm/newInstance
  5. Encode/serialize it to another ByteBuf. Get the error above.

I suspect that the atom for node name of such PID constructs with incorrect value field:

#object[io.appulse.encon.terms.type.ErlangAtom 0x1c433450 "ErlangAtom(value=nu
ll, bytes=[110, 111, 110, 111, 100, 101, 64, 110, 111, 104, 111, 115, 116], ch

k, I have fixed it.

The new version is available at the master branch and now, Travis, builds release 1.6.5 with that quick fix, after a few hours it will be available at Maven Central, and you can use it in your project.

The cause of the exception was - missing ATOM and SMALL_ATOM serialization cases, you can see it here.

Thanks again for the time which you spent on writing the issue and I hope you will enjoy working with my lib =)

Caught up 1.6.5 from maven central. Now everything works great!
Thanks a lot!
