Ekaterina Dimitrova commented on CASSANDRA-19001: ------------------------------------------------- I did not get any response to my github issues question to chronicle. The closest I found by searching into the repos was: [https://github.com/OpenHFT/Chronicle-Queue/blob/9f03bc69b8f0ec36c505108bcc2b8370e6bde798/docs/antora/modules/demos/pages/message-history.adoc#L69] Mentioning errors, but I need to test it [https://github.com/OpenHFT/Chronicle-Wire/commit/eeb1004a9635240492e3bb0d100d03737f22300f] - the commit is about performance, not sure whether if we remove those there won't be errors... need to be checked [https://github.com/OpenHFT/Chronicle-Wire/commit/9fc82fe42d414710e655ca9985eb2c151f8d38cb] - mentions that those are needed to make it possible to run the demos in the repo. So this was from high-level digging in the repos. I need to look into the details of how this relates to us. > Check whether the startup warnings for unknown modules represent a legit > problem or cosmetic issue > -------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-19001 > URL: https://issues.apache.org/jira/browse/CASSANDRA-19001 > Project: Cassandra > Issue Type: Bug > Components: Local/Other > Reporter: Ekaterina Dimitrova > Assignee: Ekaterina Dimitrova > Priority: Normal > Fix For: 4.0.x, 4.1.x, 5.0-beta, 5.0.x, 5.x > > > During the 5.0 alpha 2 release > [vote|https://lists.apache.org/thread/lt3x0obr5cpbcydf5490pj6b2q0mz5zr], > [~paulo] raised the following concerns: > {code:java} > Launched a tarball-based 5.0-alpha2 container on top of > "eclipse-temurin:17-jre-focal" and the server starts up fine, can run > nodetool and cqlsh. > I got these seemingly harmless JDK17 warnings during startup and when > running nodetool (no warnings on JDK11): > WARNING: Unknown module: jdk.attach specified to --add-exports > WARNING: Unknown module: jdk.compiler specified to --add-exports > WARNING: Unknown module: jdk.compiler specified to --add-opens > WARNING: A terminally deprecated method in java.lang.System has been called > WARNING: System::setSecurityManager has been called by > org.apache.cassandra.security.ThreadAwareSecurityManager > (file:/opt/cassandra/lib/apache-cassandra-5.0-alpha2-SNAPSHOT.jar) > WARNING: Please consider reporting this to the maintainers of > org.apache.cassandra.security.ThreadAwareSecurityManager > WARNING: System::setSecurityManager will be removed in a future release > Anybody knows if these warnings are legit/expected ?
