             Summary: Missing trailing slash with Bundle.getResource() for directory entry
                 Key: FELIX-6294
                 URL: https://issues.apache.org/jira/browse/FELIX-6294
             Project: Felix
          Issue Type: Bug
          Components: Framework
            Reporter: Grzegorz Grzybek


I'm working on Pax Web 8 and I try to unify _welcome file_ handling across Jetty/Tomcat/Undertow.
When accessing _directory entries_ from a bundle ({{org.osgi.framework.Bundle#getResource()}} I found different behavior between Felix and Equinox.

Trying to pass {{/META-INF/}} and {{/META-INF}} resource names to {{getResource()}} method, I'm getting different results for Felix:
* bundle://19.0:1/META-INF/
* bundle://19.0:1/META-INF

and Equinox:
* bundleresource://19.fwk1529115495/META-INF/
* bundleresource://19.fwk1529115495/META-INF/

Underneath, both implementations call {{java.util.zip.ZipFile#getEntry(java.lang.String)}}, but only Equniox has special {{org.eclipse.osgi.storage.bundlefile.BundleFile#fixTrailingSlash()}} method that adjusts the returned URL according to passed name and actual ZIP entry ({{java.util.zip.ZipEntry#getName()}}.

This makes detection of _a directory_ obtained from a bundle much harder with Felix. Also {{org.eclipse.jetty.util.resource.URLResource#isDirectory()}} is simply:
{code:java}
public boolean isDirectory()
{
    return exists() && _urlString.endsWith("/");
}
{code}
