Hi, we're doing plenty of iterations over Set.of() instances during bootstrap, which makes these operations show up prominently in startup profiles. This patch refactors a few hot methods to get a measureable startup improvement without regressing on targeted microbenchmarks.
Bug: https://bugs.openjdk.java.net/browse/JDK-8236641 Webrev: http://cr.openjdk.java.net/~redestad/8236641/open.00/ (The patch is baselined against 8236850) Thanks! /Claes
