[jira] [Resolved] (CALCITE-1218) Mishandling of uncaught exceptions results in no ErrorResponse sent to client

Josh Elser resolved CALCITE-1218.
---------------------------------
    Resolution: Fixed

Fixed in https://git1-us-west.apache.org/repos/asf?p=calcite.git;a=commit;h=fa87c0621fde841d2b1a40b8fb0048ed70ea576a.

One annoying piece was that I couldn't get a test written for this how I wanted to. Ultimately, this stemmed from the relocation of protobuf classes in the avatica dependency. CALCITE-1224 will address this moving forward.

> In doing some testing of the Kerberos auth for Avatica, I noticed another area (in AvaticaProtobufHandler) which did not create and return an ErrorResponse to the user. This shows up in the client with an obtuse error message of "Cannot find parser for empty message class" (or similar).
> Before 1.8.0 comes out, we need to:
> # Squash this issue once and for all (catch all exceptions and create an ErrorResponse)
> # Improve the client error message
