This is fixed for the somewhat limited manual testing I did.

But!

* the automated tests are not in place.  They shouldn't be hard to
  add though, and Eli's suggestion to put jbug.py somewhere in a
  "resources" directory is perfectly acceptable.

* Daniel Pettersson, who is now using jsonrpc.el in his DAP extension,
  tried to do more even more advanced stuff with this jsonrpc.el
  version and hit an internal sanity assertion, i.e. most assuredly
  a bug.  I haven't yet reproduced it.

* I think Daniel Pettersson would make a fine jsonrpc.el maintainer :-)
