             Summary: Byte code by OpenJDK 11 is invalid due to 
Checkerframework annotations
                 Key: CALCITE-7650
                 URL: https://issues.apache.org/jira/browse/CALCITE-7650
             Project: Calcite
          Issue Type: Bug
            Reporter: Thomas Rebele
            Assignee: Thomas Rebele


CALCITE-7649 aims to add a bytecode verification to the build. Currently it 
breaks the build, as JDK 11 produces bytecode that does not pass the check (see 
the

 of the [build 
job|https://github.com/apache/calcite/actions/runs/29096279683/job/86373530030?pr=5092]).

The Java code should be changed so that JDK 11 does not produce illegal 
bytecode.
