Fix a NPE on calling DocumentBuilderFactory::getAttribute. This issue was found during the previous JCK test (JCK-7322355). The JCK failure was from a different method call, but it appears this is the root cause.
Also in this patch: consolidates get and set properties to use the same Util methods to reduce potential errors when code changes. Test: Tier1 - 3 passed JCK test passed (will update JCK-7322355 once this patch is integrated) ------------- Commit messages: - 8354774: DocumentBuilderFactory getAttribute throws NPE Changes: https://git.openjdk.org/jdk/pull/24732/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24732&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8354774 Stats: 336 lines in 11 files changed: 220 ins; 67 del; 49 mod Patch: https://git.openjdk.org/jdk/pull/24732.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24732/head:pull/24732 PR: https://git.openjdk.org/jdk/pull/24732
