[undertow-dev] Issue with Undertow Client and SSL

[Stuart Douglas]

Try using io.undertow.protocols.ssl.UndertowXnioSsl instead of the
default XNIO one. I ended up writing a different SSL implementation
for Undertow, as Undertow and remoting had different requirements for
SSL. All the testing we do is done against the Undertow SSL
implementation.
