Review request for JDK-6760902: inconsistent behavior in bootstrap class loader for classes and resources

[Mandy Chung]

Paul,

Here is the updated webrev:
http://cr.openjdk.java.net/~mchung/jdk9/webrevs/6760902/webrev.01/

This cleans up GetResource.sh and merges with GetResource2.sh.  Also 
fixed "if (pos - lastPoc > 0)" line and javadoc typo.

thanks
Mandy
