Working on 11u backports of JDK-8218021 and JDK-8250968, I found some minor points for improvement in tests
test/jdk/sun/security/tools/jarsigner/PosixPermissionsTest.java and
test/jdk/sun/security/tools/jarsigner/SymLinkTest.java
The details
PosixPermissionsTest:
- it can run on any system, no matter if the default filesystem supports Posix or not since Posix support is only required for the zipfs which is always true.
- improve some comments for the test flow
SymLinkTest:
- make output of createByteArray prettier
- improve inline comments to ease understanding
- add an option to main for generating ZIPBYTES
- use "Files.write(Path.of(ZIPFILENAME), ZIPBYTES)" for creating the test zipfile
