Hi,
Please help review the change for JDK-8042589.
Issue: https://bugs.openjdk.java.net/browse/JDK-8042589 webrev: http://cr.openjdk.java.net/~sherman/8042589/webrev/
This is a regression caused by the following change for #JDK-8032012,
issue: https://bugs.openjdk.java.net/browse/JDK-8032012 webrev: http://cr.openjdk.java.net/~sherman/8032012/ discussion: http://mail.openjdk.java.net/pipermail/core-libs-dev/2014-February/024862.html
It appears the last optimization for the surrogates we pushed in is incomplete. We still need to check isSurrogate() in the optimized non-surrogate loop, as the "first" (checked at the very beginning) might be triggered by a non-surrogate-upper/lowercase char.
Thanks! -Sherman
