Hi,

Please review my fix for 8010325.  Some background:

The alternative string-hashing implementation[1] added to 
java.lang.String a new public method, hash32(), as well as a new private 
int field to cache the alternate hash value.

Following 8005698 [2] and 8005704 [3], the new method and field in 
String are no longer used.

By updating a couple lines in Hashtable/HashMap/WeakHashMap, the 
internal sun.misc.Hashing class can also be removed.

The webrev is here:

Thanks,
-Brent
