Subject [jira] [Commented] (CASSANDRA-10672) jacoco instrumentation breaks UDF validation
Date Mon, 09 Nov 2015 02:26:10 GMT


Russ Hatch commented on CASSANDRA-10672:

Repeated runs of with and without jacoco look good locally (for all three patches).

CI results here (I still need to pore over results and see if anything looks off):

> 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.
