The enhancement request contains a few links to the discussions of this 
method's performance at open forums.
The most frequent suggestion is to use alternatives from 3rd party 

That should prove the benefits of this fix -- by improving performance 
we can keep some users from moving away from JDK :)

grep shows that langtools would also benefit from making replace() faster.
