The key part of the fix is the guard in
TLSEngine.readthat checks if a session is active and if not, handshakes before reading. I think a similar deadlock can still occur if a mid-session renegotiation is requested while an application level read is pending. Though TLS1.3 has dropped support for renegotiation.
