> SE_BAD_FIELD|https://github.com/apache/incubator-beam/blob/58a029a06aea1030279e5da8f9fa3114f456c1db/sdks/java/build-tools/src/main/resources/beam/findbugs-filter.xml#L30]:
>  Non-transient non-serializable instance field in serializable class.
> Applies to AvroCoder fields:
> * decoder
> * encoder
> * reader
> These should likely be marked transient and ensure they are properly 
> initialized after deserialization.
> This is a good starter bug. When fixing, please remove the corresponding 
> entries from 
> [findbugs-filter.xml|https://github.com/apache/incubator-beam/blob/master/sdks/java/build-tools/src/main/resources/beam/findbugs-filter.xml]
>  and verify the build passes.
