RFR for JDK-8136365

[Jean-Francois Denise]

Hi,
asking for a review of the fix for https://bugs.openjdk.java.net/browse/JDK-8136365.

webrev: http://cr.openjdk.java.net/~jfdenise/8136365/

When jimage recreate occurs, the META-INF content is filtered-out from the Package<->Module map. This map that is iterated to create resources, so META-INF resources are lost.
The fix is to check if an archive named “META-INF” exists, if this is the case iterate its entry and create associated resources.

Thanks.
JF
