Kiley Sok created BEAM-13168:
--------------------------------

             Summary: Java 11 performance slows down around mid-October
                 Key: BEAM-13168
                 URL: https://issues.apache.org/jira/browse/BEAM-13168
             Project: Beam
          Issue Type: Bug
          Components: sdk-java-harness
            Reporter: Kiley Sok


Around Oct 20, Java 11 slows down compared to Java 8.

Query 11 is the most noticeable, but even query 0 (passthrough) looks slightly slower.

Will need to run JMH benchmark:
./gradlew :sdks:java:harness:jmh -Pbenchmark=ProcessBundleBenchmark.testTinyBundle
