Yes, the {{GaloisCounterMode}} appears to make about {{DirectBuffer}} and their
attachments
[here|https://github.com/openjdk/jdk/blob/jdk-17%2B35/src/java.base/share/classes/com/sun/crypto/provider/GaloisCounterMode.java#L866].
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.

> Fix For: 4.x

> I haven't been able to identify from the Netty docs which was the lowest
> version where JDK17 was added but we are about 40 versions behind in netty 4
> so I suspect we better update.
> We need to consider there was an issue with class cast exceptions when
> building with JDK17 with newer versions of netty (the newest available in
> March 2022). For the record, we didn't see those when running CI on JDK8 and
> JDK11. We also need to carefully revise the changes between the netty
> versions.
> Upgrading will cover also a fix in netty that was discussed in
