Shouldn't you replace `conContext.handshakeContext` with `context` in those two
lines as well?

The usual pattern is to use try { } finally { } with locks (even though in this
particular case I don't see how the assignment would throw) - but if more
things need to be done in the future here then at least the try { } finally { }
will be in place.
Suggestion:
handshakeCtxLock.lock();
try {
handshakeContext = null;
} finally {
handshakeCtxLock.unlock();
}
