When a bundle has a nested directory as a Bundle-ClassPath entry the BundleWiring.listResources method does not find any resources from the directory class path entry. This will be very problematic for scenarios that want to do classpath scanning on a web application bundle. In this case the Bundle-ClassPath will have the following: Bundle-ClassPath: WEB-INF/classes/ This is because the NestedDirBundleFile.getEntryPaths method does nothing: public Enumeration<String> getEntryPaths(String path) { // getEntryPaths is only valid if this is a root bundle file. return null; } The comment is obviously no longer correct ;-) This method gets used by BundleWiring.listResources now.
Created attachment 195601 [details] Patch + test This patch implements the org.eclipse.osgi.baseadaptor.bundlefile.NestedDirBundleFile.getEntryPaths(String) method properly.
This bug is important to fix. One of the important usecases of BundleWiring.listResources method is to enable the classpath scanning of Web Application Bundles.
John and BJ, please review for RC2.
I would make new prependNestedDir method private access. Allows the compiler to inline it.

Created attachment 195610 [details] updated patch and tests Updated patch to make prependNestedDir private. I also made the cp and baseBundleFile fields final privates.

Created attachment 195618 [details] updated patch and tests Sigh, I am not having good luck at getting the right patch attached. Lets try that again.

patch released.
