Subject [jira] [Commented] (CONNECTORS-875) LiveLink connector: LAPI exceptions not always caught
Date Wed, 05 Feb 2014 14:04:09 GMT


David Morana commented on CONNECTORS-875:

I'm just trying to restart the job.
I can't get into view the livelink repo and auth connector to see if they are working.
I can't restart the job because it just hangs on starting up and then it hangs on aborting.
tcpdump was running; we've stopped it and the job is no longer aborting.
I still can't view the livelink repo and auth connectors.

> LAPI has the ability to communicate via HTTP with the LiveLink server.  Unfortunately,
if something goes wrong on the server side, LAPI does not behave well and throws all sorts
of runtime exceptions.  For example:

> Other examples include ArrayIndexOutOfBoundsException, etc.
> It would be good to catch these and deal with them in a saner way than killing off and
restarting the worker thread.
