Karl Wright commented on CONNECTORS-875:
----------------------------------------

The refactor will not help you; it contains no functional changes.

This is not a MCF problem.  Your LiveLink server is dead.

> 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.
