             Summary: Upgrade java 11 version on the microbenchmark worker
                 Key: FLINK-29584
                 URL: https://issues.apache.org/jira/browse/FLINK-29584
             Project: Flink
          Issue Type: Improvement
          Components: Benchmarks
    Affects Versions: 1.17.0
            Reporter: Piotr Nowojski
            Assignee: Piotr Nowojski
             Fix For: 1.17.0


It looks like the older JDK 11 builds have problems with JIT in the 
microbenchmarks, as for example visible 
[here|http://codespeed.dak8s.net:8000/timeline/?ben=globalWindow&env=2]. 
Locally I was able to reproduce this problem and the issue goes away after 
upgrading to a newer JDK 11 build.
