-----------------------------------------------
Summary: Find a way to get FileDescriptor.fd and
sun.nio.ch.FileChannelImpl.fd without opening internals
Key: CASSANDRA-17850
URL: https://issues.apache.org/jira/browse/CASSANDRA-17850
Project: Cassandra
Issue Type: Improvement
Reporter: Ekaterina Dimitrova
With Java 17 if we do not add below to the jvm17 server options:
{code:java}
--add-opens java.base/sun.nio.ch=ALL-UNNAMED
--add-opens java.base/java.io=ALL-UNNAMED{code}
we get on startup (considering I comment out the scripted UDFs and apply a few
changes to the startup scripts):
