http://cr.openjdk.java.net/~iklam/jdk11/8191375-cds.tests.vmprop.v01/
Summary:
1. Added the new property "@require vm.cds.archived.heap". This replaces
various
ad-hoc settings like the following, which is hard to maintain:
* Feature support: G1GC only, compressed oops/kptrs, 64-bit os, not
on windows
* @requires (sun.arch.data.model != "32") & (os.family != "windows")
* @requires vm.cds
* @requires vm.gc.G1
2. Also did some clean up such as removing duplicated lines of "@require
vm.cds"
in some tests
3. Removed explicit settings of -XX:-UseCompressedOops, -XX:+UseGCGC,
etc, that
are now implied by "@require vm.cds" or "@require vm.cds.archived.heap"
4. Removed unnecessary '@require vm.gc == "null"' from a few test cases.
(It is only needed by tests that explicitly choose GC types, but
somehow it's
been leaked to other tests due to copy-paste).
I've tested locally with jtreg:
- no explicit setting of GC
- explicitly set GC with -vmoptions:-XX:+UseG1GC
- explicitly set GC with -vmoptions:-XX:+UseParallelGC
Testing with mach5 with tiers 1-3 now.
Thanks
