Subject: [execnet-dev] trouble with jython via execnet
Message-ID: <CALRVTp+JoFReeCEtj8EKH6zj44Z9hMkaDksT_9nOP18HGDz8nA@mail.gmail.com>

python=2.7
jython=2.5.3
execnet=1.0.9 (Also tried 1.1, 1.2)
OS=ubuntu and mac mavericks, both have the problem

I am trying to integrate jython and python code with execnet. The following
command never finishes

 python -c 'import execnet ;gateway =
execnet.makegateway("popen//python=jython"); '

If I change jython to python on the popen string, the command finishes.

The JVM appears to be blocked waiting for a message:
