[PATCH] JDK-8211765 - JarFile constructor throws undocumented exception

[Jaikiran Pai]

Thank you Chris.

I've attached a patch here which catches the InvalidPathException within
the implementation of ZipFile and wraps and throws a IOException. It's
the same patch which I mentioned earlier in this thread, but now also
includes jtreg testcase to reproduce the issue and verify the fix. I
have run the jtreg test with and without this patch on my *nix system
and it behaves as expected (fails without the fix and passes with it). I
don't have a Windows OS at hand to test this patch and the testcase on it.

I also did a very basic check and went through the JarFile/ZipFile
constructor code path to see if there are other places in that flow
which might need similar treatment. My not-so-thorough check didn't show
up any other such instance.

Could I please get help from someone who can sponsor this patch and help
with the review too?
