      Description

        It seems that there exists a memory/performance regression that was introduced with JDK-8210985: Update the default SSL session cache size to 20480.

        The idea to limit the maixmum SSL session cache size by itself is good. Unfortunately, as per the current implementation of sun.security.util.MemoryCache, it also modifies the initial size of the LinkedHashMap that is backing the cache to initialize with more than the maximum size.
