      Description

      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
