Bug: During SSL handshake error, netty complains that exceptionCaught() was not handled
Status: Resolved | Priority: Major | Resolution: Fixed
Created: 06/Apr/23 13:09

I was chaos testing the new native TLS, forcing a certificate to expire and fail handshake. The handshake failure properly causes submitted requests to fail, but I see the following "unhandled exception" like message:
{code:java}
WARN  o.a.h.t.i.n.c.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
