Ekaterina Dimitrova commented on CASSANDRA-18180:
-------------------------------------------------
A few notes from CASSANDRA-17992:
When using JDK provider and not OpenSSL, the class cast exception is there with
JDK17, no matter of Netty Version. We do not see the issue in Python DTests as
they seem to rely on OpenSSL.
For the record, comment by [~benedict] on CASSANDRA-17992:
{quote}Yes, the GaloisCounterMode appears to make about DirectBuffer and their
attachments here.
bq. Looking again at the rest of the JDK, I'm not actually sure attachments can
be accessed publicly, so this is probably our problem rather than the JDK's.
However, we might be able to fix it by simply having Chunk implement
DirectBuffer, and having it return its address.
