Bill Huang has updated the pull request incrementally with one additional commit since the last revision: Remove unused JTREG_VALUE_CLASS_ANNOTATION_JAR and guard the -cpa: plugin JAR option behind JTREG_VALUE_CLASS_PLUGIN to avoid adding it to the classpath when the plugin is not active. ------------- Changes: - all: https://git.openjdk.org/valhalla/pull/2253/files - new: https://git.openjdk.org/valhalla/pull/2253/files/35b5071e..c9ef9829 Webrevs: - full: https://webrevs.openjdk.org/?repo=valhalla&pr=2253&range=08 - incr: https://webrevs.openjdk.org/?repo=valhalla&pr=2253&range=07-08 Stats: 8 lines in 1 file changed: 3 ins; 5 del; 0 mod Patch: https://git.openjdk.org/valhalla/pull/2253.diff Fetch: git fetch https://git.openjdk.org/valhalla.git pull/2253/head:pull/2253 PR: https://git.openjdk.org/valhalla/pull/2253
