Build changes look good to me (but should probably get review from someone else).

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! Calvin, Ioi, Jiangli
