Hi Ioi,

I found this old bug where I think the reversing was added: https://bugs.openjdk.java.net/browse/JDK-4994483

This seems to be used only by CDS dumping, and if I remove the call nothing bad seems to happen. Does anyone know what hashtable::reverse() could possibly achieve?

Also, there's another variant that seems to be dead code that no one calls. template <class T, MEMFLAGS F> void Hashtable<T, F>::reverse(void* boundary) - Ioi
