>
> According to https://github.com/netty/netty/issues/832, there is a JDK issue
> during garbage collection when the SSL session cache is not limited. We
> should allow the user to configure this and further (advanced) SSL parameters
> for fine-tuning to fix this and similar issues. In particular, the following
> parameters should be configurable:
> - SSL session cache size
> - SSL session timeout
> - SSL handshake timeout
> - SSL close notify flush timeout
