Hi, please review this patch to get rid of the back-to-back lookup of name and name+'/' in ZipFile.getEntry. This is done by first adjusting the hash function so that a trailing slash is not included in an entry's hash code, and adjusting appropriately when matching the arrays.
This means we do fewer table lookups, less arithmetic and potentially less allocation on lookup misses. Patch contributed by Eirik Bjørsnøs. Webrev: http://cr.openjdk.java.net/~redestad/8242959/open.00/ Bug: https://bugs.openjdk.java.net/browse/JDK-8242959 Testing: tier1+2, verified neutral performance for hits and a significant reduction in cost of misses (~30-50ms improvement on Spring PetClinic startup). Thanks! /Claes
