RFR: 8176834: jdk/nio/zipfs/MultiReleaseJarTest.java test fails after JDK-8176709

[Claes Redestad]

Hi,

it appears the test we wrote to test the Multi-Release checking in
JarFile, based on the jar manifest specification[1] and now adapted
for JDK-8176709 is too strict when actually using
java.util.jar.Manifest, which means the test I added for JDK-8176709
fails on the version that I pushed (but not on the version I tested it
on - shame! shame!)

Webrev: http://cr.openjdk.java.net/~redestad/8176834/jdk.01/
Bug: https://bugs.openjdk.java.net/browse/JDK-8176834

I've filed a bug to re-examine the Manifest
specification/implementation here, which may or may not need to be
higher priority:

Thanks!
