[10] RFR 8186654 : Poor quality of sun.security.util.Cache.EqualByteArray.hashCode()

[Ivan Gerasimov]

Hello!

An auxiliary class EqualByteArray implements hashCode() in a way that 
small changes to the content do not change the hash value.

It is proposed to reuse Arrays.hashCode(byte[]) for the hash code 
calculations.

Also, the private int hash is made non-volatile, as it removes accessing 
to a volatile variable in the relatively frequently executed code for 
the price of relatively less likely chance of a double hash code 
calculation.  (For reference, java.lang.String uses the same approach.)

Would you please help review the fix?
