> This patch exposes a couple of intrinsics used by String to speed up ASCII > checking and byte[] -> char[] inflation, which can be used by latin1 and > ASCII-compatible CharsetDecoders to speed up decoding operations. > > - Fast-path implemented for all standard charsets, with up to 10x performance > improvements in microbenchmarks reading Strings from ByteArrayInputStream. > - Cleanup of StreamDecoder/-Encoder with some minor improvements when > interpreting > - Reworked creation of JavaLangAccess to be safely published for > CharsetDecoders/-Encoders used for setting up System.out/in. As JLA and these > encoders are created during System.initPhase1 the current sequence caused the > initialization to became unstable and a few tests were consistently getting > an NPE. > > Testing: tier1-3
