JDK-8341775: In the case where there is a *single* META-INF directory but potentially *multiple* manifest files of different cases, print a warning before selecting the first one and ignoring the rest (the current behavior should be maintained).
**Note**: We cannot (so far) pass whether the verbose flag is set to the class that does this processing. We may want to add a property to the builder for this. As-is, the message will be printed via `System.err` whether verbose is set or not. ------------- Commit messages: - JDK-8341775: In the case where there is a *single* META-INF directory but potentially *multiple* manifest files of different cases, print a warning before selecting the first one and ignoring the rest.
