[Col] Collator - Faster Comparison for identical strings.

A DESCRIPTION OF THE REQUEST :
Collator (RuleBasedCollator?) does not check the compared strings for == before going into the complex rules for comparison.

JUSTIFICATION :
It seems silly to compare every character of a string to itself to determine what will amount to equality. Collator .getInstance() is called from TableRowSorter for all String sorting. JTables do often have duplicated data. The test program shows a significant speed increase. Although Collator is still very slow compared to String.compateTo() or String.CASE_INSENSITIVE_ORDER. I assume this is because of Unicode support. It would be great if the US/English Collator was as fast as String.compateTo().

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Collator should check for == before moving on to the complicated comparisons.

CUSTOMER SUBMITTED WORKAROUND :
private Comparator<String> compareTestEq = new Comparator<String>(){

@Override
public int compare(String o1, String o2) {
if(o1 == o2){
return 0;
}
return Collator.getInstance().compare(o1, o2);
}

};
