Hello!

FieldReflectorKey class contains a combined-string representation of the 
fields (their names and signatures).

This string is used for calculating the hash code and comparing two 
FieldReflectorKey objects for equality, which is expensive.

It is proposed to store the names and signatures (which are likely to be 
interned) in an array an use this array for both tasks utilizing 
Arrays.hashCode() and Arrays.equals().

Would you please help review the fix?
