Description
(This is a tck-red/conformance clone of JDK-8065536)

Spec for the methods
http://docs.oracle.com/javase/8/docs/api/java/util/zip/ZipEntry.html#setCreationTime-java.nio.file.attribute.FileTime-
http://docs.oracle.com/javase/8/docs/api/java/util/zip/ZipEntry.html#setLastAccessTime-java.nio.file.attribute.FileTime-

says:

"Throws:
NullPointerException - if the time is null"


However the implementation doesn't satisfy this assertion, the following code will produce no exceptions:

        new ZipEntry("entry").setCreationTime(null);
        new ZipEntry("entry").setLastAccessTime(null);
        new JarEntry("entry").setCreationTime(null);
        new JarEntry("entry").setLastAccessTime(null);


The following JCK9 tests will fail due to this:

api/java_util/jar/JarEntry/autd2.html#CreationTime[nullCreationTime]
api/java_util/jar/JarEntry/autd2.html#LastAccessTime[nullCreationTime]
api/java_util/zip/ZipEntry/autd2.html#LastAccessTime[nullCreationTime]
