Alas, `gradlew precommit` from the command-line on Linux box is still angry
for me:
```
> Task :lucene:misc:compileJava
/l/trunk/lucene/misc/src/java/org/apache/lucene/misc/store/DirectIODirectory.java:163:
warning: ExtendedOpenOption is internal proprietary API and may be removed in
a future release
com.sun.nio.file.ExtendedOpenOption.DIRECT);

/l/trunk/lucene/misc/src/java/org/apache/lucene/misc/store/DirectIODirectory.java:282:
warning: ExtendedOpenOption is internal proprietary API and may be removed in
a future release
channel = FileChannel.open(path, StandardOpenOption.READ,
com.sun.nio.file.ExtendedOpenOption.DIRECT);
^
error: warnings found and -Werror specified
```
Oh I see -- you are using `@SuppressForbidden` (which is indeed necessary,
since we are using an API that we otherwise forbid!), but you must also add
`@SuppressWarnings("sunapi")` to suppress `javac` warnings. Lots of
suppression happening here!! Hmm, but when I tried adding those two lines
locally, `gradlew precommit` still fails, hrmph.
This might be a JDK difference -- I'm using JDK 15.
Hmm, a little more research uncovers
[JDK-6476630](https://bugs.openjdk.java.net/browse/JDK-6476630), which makes it
sound like it is not possible to suppress this particular warning. Now I'm not
sure what to do! Need @uschindler help again!
