Actually it can be:  Consider the following:


        try (JarFile jf = new JarFile(SIGNED_VALID_ENTRY_NAME_JAR.toFile(), 
true)) {
            var ze = new ZipEntry("org/gotham/Batcave.class");
            var ex= expectThrows(ZipException.class,
                    () -> jf.getInputStream(ze) );
            // Validate that we receive the expected message from
            // JarFile::verifiableEntry when ZipEntry::getName returns null
            assertTrue( ex != null && ex.getMessage().equals("Error: ZipEntry 
should not be null!"));
        }


The above code does generate the error.
