Work Description: jklukas commented on issue #6586: [BEAM-5638] Exception
handling for Java single message transforms
URL: https://github.com/apache/beam/pull/6586#issuecomment-428699957
I pushed a new commit that adds an `ExceptionT` type parameter to `Failure`
and uses `AvroCoder` for encoding `Exception` subclasses. This is still
vulnerable to the fact that `Exception` subclasses are only transcodable with
`AvroCoder` if they have a no-arg constructor, but I try to mitigate that by
failing fast with a friendly error message that suggests a workaround.
