It did help some, yes. I'm trying to get to a point where I can
reproduce the issue because it isn't immediately clear why that last
record is causing the ShortBufferException. I'm hoping there's a way to
do that without having to hit that discord server. Ideally I'd need to
turn this into some kind of regression test that more easily isolates
the issue.

Hi there,
Did the debug log help at all or should I try to gather more
informations from the user ?

asked the original reported of the issue to provide some in the

Hi Norman,
If you are able to reproduce this issue, would you mind post the
JSSE debug log (by using Java System Property, "javax.net.debug=all")?
Please feel free to submit a bug.
Thanks & Regards,

Hi there,
We recently received a bug report in netty when JDK12 is used with
ChaCha chiphers:
https://github.com/netty/netty/issues/9150
Basically it seems like there is a problem in how it uses the
ByteBuffer internally:

Unfortunately I have no standalone reproducer yet but I just
wanted to bring it up here in case it helps.
It only happens on JDK12 it seems. Check the Netty issue for more
details…
