Hi, Please help review the fix for #8030179
issue: https://bugs.openjdk.java.net/browse/JDK-8030179 webrev: http://cr.openjdk.java.net/~sherman/8030179/webrev This is the regression bug introduced in jdk7 when trying to optimize the single byte encoding loop, in which the "optimization" code inappropriately updates the "sl" (source limit) value and triggers misbehavior of the sgp parser (in which it mistakenly returns "underflow" when it sees a high surrogate but can't see the next low surrogate, because the "sl" is changed...) Thanks! -Sherman
