             Summary: jacoco instrumentation breaks UDF validation
                 Key: CASSANDRA-10672
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10672
             Project: Cassandra
          Issue Type: Bug
            Reporter: Russ Hatch
            Assignee: Russ Hatch
             Fix For: 3.2


The jacoco agent injects a synthetic method into UDF classes as part of instrumentation for
code coverage. Currently the UDF code checks the method count on java UDF classes, and it
fails due to the jacoco synthetic method increasing the method count.

This causes a number of false test failures when running unit tests with jacoco instrumentation.

A simple fix is just to ignore synthetic methods in the counting process.
