Provide Exceptions for unsupported operations with APPLICATION_UNKNOWN ---------------------------------------------------------------------- Key: ISPN-10964 URL: https://issues.redhat.com/browse/ISPN-10964 Project: Infinispan Issue Type: Enhancement Components: Server Affects Versions: 10.1.0.Beta1 Reporter: Ryan Emerson Priority: Major The default media type for cache types is APPLICATION_UNKNOWN if not explicitly configured by the user. However, APPLICATION_UNKNOWN is not supported when using the following: * Filters * Converters * Transcoders (works sometimes, best effort) Instead of failures occurring at runtime, we should throw a configuration exception where possible. In the case of the transcoder, we should either throw a more meaningful exception when transcoding fails or remove the ability to transcode APPLICATION_UNKNOWN sources. The exception(s) should instruct the user to explicitly configure the media type.
