[jdk21u-dev] RFR: 8326897: (fs) The utility TestUtil.supportsLinks is wrongly used to check for hard link support

Tue Feb 3 13:13:02 UTC 2026

I backport this for parity with 21.0.11-oracle.

resolved two files:

test/jdk/java/nio/file/Path/ToRealPath.java
Omitted two test cases that are not in 21.
test/jdk/java/nio/file/attribute/PosixFileAttributeView/Basic.java
Trivial resolve.

Both depend on https://bugs.openjdk.org/browse/JDK-8306882: (fs) Path.toRealPath(LinkOption.NOFOLLOW_LINKS) fails when "../../" follows a link
