Description
The Dataflow ITs fails with a class version mismatch. I believe the Dataflow v1 container that is being tested was built with the wrong JDK version.
Jenkins: https://ci-beam.apache.org/job/beam_PostCommit_Java_DataflowV1/1427/#showFailuresLink
Example Failure:
java.lang.RuntimeException: java.lang.RuntimeException: org.apache.beam.sdk.util.UserCodeException: java.lang.UnsupportedClassVersionError: org/apache/commons/logging/LogFactory has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 at org.apache.beam.runners.dataflow.worker.GroupAlsoByWindowsParDoFn$1.output(GroupAlsoByWindowsParDoFn.java:187) at org.apache.beam.runners.dataflow.worker.GroupAlsoByWindowFnRunner$1.outputWindowedValue(GroupAlsoByWindowFnRunner.java:108) at org.apache.beam.runners.dataflow.worker.util.BatchGroupAlsoByWindowReshuffleFn.processElement(BatchGroupAlsoByWindowReshuffleFn.java:56) at org.apache.beam.runners.dataflow.worker.util.BatchGroupAlsoByWindowReshuffleFn.processElement(BatchGroupAlsoByWindowReshuffleFn.java:39)
