Patch for JDK-6695402: Jarsigner with multi-byte characters in class names

[Weijun Wang]

Hi Philipp

The change is now at http://hg.openjdk.java.net/jdk10/master/rev/f60a42d4b8cd.

I only moved the test to its new directory. Everything else unchanged.

Thanks again for your contribution, looking forward for more!

In fact I was quite a bit surprised when I found out that JarUtils.createJar adds the file name as contents if the file cannot be found. Ideally, we would also add some note about why this was relevant, about the test not compiling on certain oses with jtreg together with the acute but it doesn't apply any longer now. Altogether the test has become even simpler now.

I thought testName was too ambiguous a name and changed it to testClassName. I also reviewed and slightly changed a few comments again. Of course it will never become perfect but now it should do. See attached patch.
