…ntext Motivation: With the Netty ref-counted OpenSSL implementation the parent SslContext maintains state necessary for the SslEngine's it produces. However, it's possible for the parent context to be closed and release those resources before the child engines are finished which causes problems. Modification: Spawned ReferenceCountedOpenSslEngine's retain a reference to their parent ReferenceCountedOpenSslContext. Result: The lifetime of the shared data is extended to include the lifetime of the dependents.

maintains state necessary for the SslEngine's it produces. However, it's
possible for the parent context to be closed and release those resources
before the child engines are finished which causes problems.
Modification:
Spawned ReferenceCountedOpenSslEngine's retain a reference to their
parent ReferenceCountedOpenSslContext.
