This all looks good to me (of course, I'm not an official reviewer). The
new base testcase for zipfs related testing is definitely going to help
in future fixes/enhancements.

I just had one question in there:

+++ new/test/jdk/jdk/nio/zipfs/testng/util/ZipFsBaseTest.java	
...

+                {Map.of("create", "true", "noCompression", "true"),
+                        ZipEntry.STORED},
+                {Map.of("create", "true", "noCompression", "false"),
+                        ZipEntry.DEFLATED}

From what I had read in the javadoc of the private method getDefaultCompressionMethod in jdk.nio.zipfs.ZipFileSystem,
the "noCompression" property is only there for backward compatibility reasons and the new way
of configuring this semantic is the use of "compressionMethod" property (with value of either STORED
or DEFLATED). Is the use of "noCompression" in this base test class intentional or is it just a personal preference?
I'm fine either way, but wanted to know if I should stick to this form in any future test cases.
