Please review a simple fix for an NPE in doclint, in JDK 17. The NPE is caused by checking if an unknown tag is self-closing. The fix is to move the check into the arm of the preceding `if` statement that ensures that the tags is not null. Effectively, we do not valid whether unknown tags may be self-closing.
The potential for the NPE has been there a long time. The check that triggers the NPE became more likely when we removed support for HTML4. ------------- Commit messages: - JDK-8264843: Javac crashes with NullPointerException when finding unencoded XML in <pre> tag Changes: https://git.openjdk.java.net/jdk17/pull/86/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk17&pr=86&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8264843 Stats: 32 lines in 3 files changed: 28 ins; 1 del; 3 mod Patch: https://git.openjdk.java.net/jdk17/pull/86.diff Fetch: git fetch https://git.openjdk.java.net/jdk17 pull/86/head:pull/86 PR: https://git.openjdk.java.net/jdk17/pull/86
