> Though only one entry is found within META-INF, e.g.
> {{{}META-INF/groovy/org.codehaus.groovy.source.Extensions{}}}, two entries
> are retrieved via {{getResources}} method.
> {code:java}
> def loader = this.class.classLoader
> def r =
> loader.getResources("META-INF/groovy/org.codehaus.groovy.source.Extensions").toList()
> println r
> {code}
> Output:
> {code:java}
> [jar:file:/D:/_DEV/Groovy/groovy-4.0.14/lib/groovy-4.0.14.jar!/META-INF/groovy/org.codehaus.groovy.source.Extensions,

> should be avoided.
