Robert Stupp commented on CASSANDRA-10672:
------------------------------------------
The general approach looks good to me. But do we need the {{List}} there? An
{{int}} to count the non-synthetic methods should work, too.
Question: do we need that just for trunk or also for 2.2 and 3.1?

>
> 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.
