      Use this form to file an issue for test failure:

      Initial investigation:

      This is happening in beam_PostCommit_Java_PortabilityApi and beam_PostCommit_Java_ValidatesRunner_PortabilityApi_Dataflow that I know of. Tests are failing with the following error:

      java.lang.RuntimeException:
      java.util.concurrent.ExecutionException:
      java.lang.RuntimeException: Error received from SDK harness for instruction -1293:
      org.apache.beam.sdk.util.UserCodeException:
      java.lang.IllegalStateException:
      java.lang.ClassCastException: [B cannot be cast to java.lang.String
          at org.apache.beam.sdk.coders.StringUtf8Coder.encode(StringUtf8Coder.java:37)
          at ...
      

      Based on the timing of when these issues popped up, I suspect the error might be due to https://github.com/apache/beam/pull/7316.
