Add jlink plugins to allow branding change for java.vendor, java.vm.vendor and java.vendor.url.
The jlink plugin will change the value in java.lang.VersionProps, which will set those property values. The `java.vm.vendor` was initialized by VM with value set at build time, and then later be replaced with value from VersionProps. To keep current behavior, we treat 'N/A' value as no-op to mimic current build behavior. Perhaps we don't really need this, as proper value should be set with `branding.conf` in official build. ------------- Commit messages: - Avoid N/A used as java.vm.vendor value as currently build behavior - 8342035: jlink plugins for setting java.vendor, java.vm.vendor and java.vendor.url Changes: https://git.openjdk.org/jdk/pull/21964/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=21964&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8342035 Stats: 224 lines in 14 files changed: 213 ins; 5 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/21964.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/21964/head:pull/21964 PR: https://git.openjdk.org/jdk/pull/21964
