Please review this small change that improves testability of CDS,
and will aid in fixing several intermittently failing CDS tests.
JBS: https://jbs.oracle.com/bugs/browse/JDK-8033990
Webrev: http://cr.openjdk.java.net/~mseledtsov/8033990/webrev.00/
Testing:
Basic testing:
- ran "Xshare:auto -version", "-XX:+Verbose
-XX:+PrintMiscellaneous -Xshare:auto -version" before and after the
archive was created
- ran "XX:+Verbose -XX:+PrintMiscellaneous -Xshare:auto
-version" on Windows where ASLR occasionally prevents sharing
JT-Reg: runtime/SharedArchiveFile, with and w/o the additional
options -vmoptions:"-XX:+Verbose -XX:+PrintMiscellaneous"
Tonga: a sub-set of vm.parallel_class_loading.testlist, with
-Xshare:auto -XX:+Verbose -XX:+PrintMiscellaneous -showversion"
Tonga (vm.parallel_class_loading.testlist -vmopts
" -Xshare:auto -XX:+Verbose -XX:+PrintMiscellaneous -showversion")
- ongoing. Plan not to run full testlist since the change
is small and trivial
JPRT: standard JPRT: 2014-02-07-210345.mseledtsov.work01
- ongoing
Thank you,
Misha
