Class ALPNHackSSLEngine

java.lang.Object

javax.net.ssl.SSLEngine

io.undertow.protocols.ssl.ALPNHackSSLEngine

public class ALPNHackSSLEngine
extends SSLEngine

SSLEngine wrapper that provides some super hacky ALPN support on JDK8. Even though this is a nasty hack that relies on JDK internals it is still preferable to modifying the boot class path. It is expected to work with all JDK8 versions, however this cannot be guaranteed if the SSL internals are changed in an incompatible way. This class will go away once JDK8 is no longer in use.
