```
public abstract class ReferenceCountedOpenSslContext
extends SslContext
implements ReferenceCounted
```
An implementation of SslContext which works with libraries that support the OpenSsl C library API.
Instances of this class must be released or else native memory will leak!
Instances of this class must not be released before any ReferenceCountedOpenSslEngine which depends upon the instance of this class is released. Otherwise if any method of ReferenceCountedOpenSslEngine is called which uses this class's JNI resources the JVM may crash.
