When trying to get a FileAttributeView from a zip entry JDK 17+ throws an undeclared UnsupportedOperationException. The javadoc of Files.getFileAttributeView() says:

https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/nio/file/Files.html#getFileAttributeView(java.nio.file.Path,java.lang.Class,java.nio.file.LinkOption...)
"""
Returns:
    a file attribute view of the specified type, or null if the attribute view type is not available
"""

Yet, an exception is thrown in some cases. That is a regression to JDK 11. See the attached reproducer.

JDK 11 run:
--------------------------
Debug: Creating test-zip-file.zip...
Debug: reading entry: /noperm_entry
Debug: os.name == Linux
Non-Windows Test PASSED! env=posix view=null, featureVersion: 11
Debug: reading entry: /noperm_entry
Debug: os.name == Linux
Non-Windows Test PASSED! env=empty view=null, featureVersion: 11

JDK 17+ runs:
--------------------------
Debug: Creating test-zip-file.zip...
Debug: reading entry: /noperm_entry
Debug: os.name == Linux
Non-Windows Test PASSED! env=posix view=jdk.nio.zipfs.ZipPosixFileAttributeView@2f2c9b19, featureVersion: 17
Debug: reading entry: /noperm_entry
Debug: Files.getFileAttributeView() threw exception: java.lang.UnsupportedOperationException: view <interface java.nio.file.attribute.PosixFileAttributeView> is not supported
Debug: os.name == Linux
Exception in thread "main" java.lang.RuntimeException: Test failed! view=null
	at TestPosixAttributeView.runTest(TestPosixAttributeView.java:83)
	at TestPosixAttributeView.main(TestPosixAttributeView.java:105)

This was originally reported here, where the issue is that on Windows, where Posix permissions are not supported, suddenly throws an exception when it didn't before JDK-8213031:

Fix request (15u) I'd like to backport it to 15 where this issue exists, too. Applies perfectly barring a comma in copyright. All zipfs tests pass OK.

Fix Request (OpenJDK 17u): Please approve backporting this fix to 17u. The problem exists there too and was actually discovered as a change in an 11->17 upgrade attempt. The JDK 18 change applies clean and no regressions observed. Should be low risk (return null instead of throwing an undeclared exception).

Looks like line 71 which throws UnsupportedOperationException, should just return null as UnixFileSystemProvider does

[~clanger] Perhaps you want to have a look at this?
