RFR (S) 8136500: Integer/Long getChars and stringSize should be more idiomatic

Hi, We have discovered this both in Compact Strings and Indy String Concat work, but it deserves to be treated separately. Integer/Long getChars code seems to be very old (Josh Bloch estimated circa 1994) and written under the assumption no compiler is here to help us. Fast-forward 20 years, and

Frederic, Code review for web revs you sent out. Code looks good. I am not as familiar with the compiler code. I realize you need to check in at least a subset of the java.util.concurrent changes for the test to work, so maybe I should not have asked Doug about his preference there. Sorry. I a

Totally appreciate the suggestion that the java.util.concurrent modifications be done by folks with more domain expertise. Would you have us incorporate the initial minimal set of j.u.c. updates or none at all? thanks, Karen > On Nov 11, 2015, at 8:09 PM, Doug Lea wrote: > > On 11/10/2015 12:

Alexander, I see your point. It is also out of spec for Handler.setFormatter to actually call Formatter.setErrorManager. What if there are subclasses of formatter that exist today with a setErrorManager method? Also not all handlers have one formatter or actually call super.setFormatter sinc

jdk.scripting.nashorn is loaded by the extension class loader. Is jdk.dynalink expected to be loaded by the ext. class loader? You need to edit this file to include the new module: jdk/make/src/classes/build/tools/module/ext.modules This is an interim file to map modules to class loader and
