> Currently, Proxy.isProxyClass is used in findNonNullKeyEntry method to judge whether
a key object is a proxy object or not. However, that will degrade the performance of HashMap
since isProxyClass method is synchronized. Actually,  Proxy.isProxyClass can be removed if
we use an improved solution to support proxy object as the key.
