Problem is that [JDK-8286850](https://bugs.openjdk.org/browse/JDK-8286850) never set correct value in .jpackage.xml to mark image as signed. [JDK-8289030](https://bugs.openjdk.org/browse/JDK-8289030) reads this value to check if we can add per-user and system wide configuration to packaged app. Fixed by setting correct value in .jpackage.xml when we signing predefine application image.
Added tests to cover this case and added check for values inside .jpackage.xml to validate signed and Mac App Store values. ------------- Commit messages: - 8293462: [macos] app image signature invalid when creating DMG or PKG from post processed signed image Changes: https://git.openjdk.org/jdk/pull/10316/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=10316&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8293462 Stats: 367 lines in 12 files changed: 303 ins; 15 del; 49 mod Patch: https://git.openjdk.org/jdk/pull/10316.diff Fetch: git fetch https://git.openjdk.org/jdk pull/10316/head:pull/10316 PR: https://git.openjdk.org/jdk/pull/10316
