Planning to integrate this into 27 and create a backport to 26

The relevant test is jdk/javadoc/doccheck/checks/jdkCheckLinks.java, which is currently problem-listed and will be turned back on via [JDK-8370249](https://bugs.openjdk.org/browse/JDK-8370249). It fails before this fix, passes afterwards (when I take it off the problem list).
