[rickie]

This could be related to #1250. Are you passing the following compiler argument -XepDisableWarningsInGeneratedCode (related comment)?

I'd also suggest to upgrade to the latest version of Error Prone 2.14.0. As version 2.3.4 quite an old version.

Could you provide some minimal repro?

If you have a minimal repro for the latest version of Error Prone, please add it to #1250
