[jira] Commented: (HARMONY-6070) [luni] Improve Long.toString(long) performance

Tim Ellison commented on HARMONY-6070:
--------------------------------------

Jim, can you give an example of where creating the String representation of a Long is going to be critical?  We should either apply the patch or reject it now.

> Based on the algorithm for HARMONY-6068, I've made a patch for Long.toString(long). Since the big long numbers can have much more digits than integers, this algorithm can improve the performance a lot for big long numbers.
