RFR: JDK-8232170: FSInfo#getJarClassPath throws an exception not declared in its throws clause

[Jaikiran Pai]

Can I please get a review and a sponsor for a fix for JDK-8232170[1]? I
have the patch available as a webrev at [2]?

The patch only deals with catching the java.nio.file.Path usage related
exceptions and then rethrows them as IOException. The original
discussion is available at [3]. In that discussion, David had mentioned
that the existing usage of java.nio.file.Path may not be the right thing
to do and might need changes. This patch does not address it since that
change I think will need more broader discussion and review.

The patch also contains a jtreg test to reproduce this issue and verify
the fix.
