RFR: 8139067: Re-examine if a consumer module should load bundles from unnamed module

[Masayoshi Okutsu]

Hello,

Please review the change for JDK-8139067. A consumer module 
(ResourceBundle.getBundle caller) will no longer load resource bundles 
from the class-path if the consumer module is a named module. Test 
programs, basic and modlocal, have been changed to confirm .properties 
bundles are not loaded from a jar file on the class-path.The webrev also 
include some cleanup of @bug and @summary for the test programs.

Issue: https://bugs.openjdk.java.net/browse/JDK-8139067

Webrev: http://cr.openjdk.java.net/~okutsu/9/8139067/webrev.00

Thanks,
Masayoshi
