New issue 323 by matt...@douglasstribe.com: Add SupprrssWarnings to
generated Java code
http://code.google.com/p/protobuf/issues/detail?id=323

The generated Java code for protocol buffers has many warning if compiled
in a project set to a high warning level. It would be convenient if all
classes generated by protocol buffers were tagged with
@SuppressWarnings(value="all")

For Java 6+ targeted code, an @javax.annotation.Generated annotation should
also be added with the date and an identifier (e.g. "com.google.protobuf")
to help static analysis tools identify the generated code.

Or maybe if we can marked as generated
like adding some marker annotation
@javax.annotation.Generated (but this is only valid from 1.6+)

This would be huge. I will end up having to write some post processor to
add this to the code and I would prefer not to.

Preferable something like this...

import javax.annotation.Generated;

@Generated(value="protoc", date="2013-12-19T12:33:56+00:00",
comments="Generated by the Google Protocol Buffer compiler.")
@SuppressWarnings({"PMD", "all"})

Using the annotation "javax.annotation.Generated" seems to be the right
approach. There is a duplicate issue on github:
