[Hawkular-dev] inventory - /graph - IOException: Pipe not connected

[Gareth Healy]

I've created some entities via /bulk and can get them back via /traversal.
But when i call /graph i get back: IOException: Pipe not connected

Error message:

After a bit of debugging, i believe its because the InputStream [1] hasn't
been fully written to, as the graph is retrieved on another thread [2],
which means the REST call has returned and closed.

Should this endpoint not use a latch/wait or AsyncResponse.resume like the
metrics APIs does? As i am able to get the graph back, if i keep the
connection alive via debug checkpoints.

Cheers.
