Invalid non-JSON request ("Unexpected character") results in `SERVER_UNHANDLED_ERROR` 500 failure #1200

Closed tatu-at-datastax closed 6 days ago

Going through unmapped exceptions in Splunk logs, I see exceptions like:

Unrecognized exception caught, mapped to SERVER_UNHANDLED_ERROR: Unexpected 
character ('d' (code 100)): was expecting double-quote to start field name

which suggests invalid payload (malformed "JSON") where client sends unquoted JSON Field names

{debug: true}

Or something.

Unfortunately logging currently does not include source content (will file separate issue for enabling)

Full stack trace:
