Thank you for tacking the conversion of this test to junit

One quick comment, if we are updating this test, we should look to get rid of input.zip which means we should also address as part of the change:

open/test/jdk/java/util/zip/ZipFile/EnumAfterClose.java
open/test/jdk/java/util/zip/ZipFile/FinalizeInflater.java
open/test/jdk/java/util/zip/ZipFile/StreamZipEntriesTest.java
