Please review the implementation for JEP JDK-8204247
(https://bugs.openjdk.java.net/browse/JDK-8204247). The goal of the JEP
is to include a default CDS archive in JDK 12 binary distribution
(downloadable from http://jdk.java.net/12/). The default CDS archive is
generated using the default classlist (resides in the lib/ directory) at
JDK build time. Any comments/suggestions are highly appreciated.
All makefile changes in the webrev are contributed by Erik Joelsson
(many thanks!!).
This is a combination of efforts from different teams and individuals.
Thanks to everyone who has been involved in the JEP & implementation
discussions, testing and bug fixing!
JEP: https://bugs.openjdk.java.net/browse/JDK-8204247
RFE: https://bugs.openjdk.java.net/browse/JDK-8202951
webrev: http://cr.openjdk.java.net/~jiangli/8202951/webrev.00/
Two sanity test cases for the default CDS archive are included
test/hotspot/jtreg/runtime/SharedArchiveFile. They are not intended for
in-depth CDS functional testing, which is already covered by the
existing cds/appcds tests and all tiered tests executing with the
default CDS archive enabled.
As part of the webrev,
test/jdk/javax/imageio/plugins/png/ItxtUtf8Test.java is also fixed to
use larger java heap (JDK-8209739
, https://bugs.openjdk.java.net/browse/JDK-8209739).
Tests executed:
- several rounds of tier1 - tier8 via mach5
- JCK lang, api and vm tests via mach5
Thanks!
