Jetty uncaught exception via jsapi/input_table.html

[devinrsmith]

Part of #1744

When adding to an input table via http://localhost:10000/jsapi/input_table.html, server-jetty has an uncaught exception, and prints a stacktrace out to STDERR:

The input table does get updated correctly.

I've tried, but can't reproduce this via the java client - so might be jsapi specific in some respects.

Also, this exception does not seem to occur (or is swallowed?) when running server-netty.

As a follow up to this ticket, or as part of this ticket, we may want to see what sort of logging hooks we can get into jetty to pipe uncaught exceptions through our logger.
