The fix for https://bugs.openjdk.java.net/browse/JDK-8245527 introduced an internal property "jdk.internal.sasl.tlschannelbinding" which is used to pass the channel binding application data to the Sasl client.

We have a custom Sasl client which support a native GSS implementation for Windows. The client needs to read this property in order to pass the application data to the native initialize and accept methods.

It would be better if the property jdk.internal.sasl.tlschannelbinding was renamed to some public value and the property documented.
