------------------------------------
Oh, it's {{ClientExceptionsUtil}}. Took me a moment :)
Thanks for taking a look, [~eclark]. Let me see if I can address your concerns.

> Follow-on for HBASE-15221:
> A work-around was added in HTableMultiplexer to work around an issue that
> AsyncProcess wasn't clearing the region location cache on Exception. This was
> stemming from the issue that the {{tableName}} is {{null}} because
> HTableMultiplexer is using the {{multi}} RPC. This causes an error that looks
> like:
> {noformat}
> [WARN] Coding error, see method javadoc. row=[B@1673eff, tableName=null
> {noformat}
> HBASE-15221 should fix HTableMultiplexer, but it would be good to push the
> fix down into AsyncProcess instead of using higher-level workarounds.
