Hi, I am currently using a 3rd party component in a small project of mine. This component tries to dynamically load resources from a given URL, it does this by trying several extensions for a base name, and returns success when it finds a resource that matches the base name and extension. For this dynamic loading it depends on URL.openStream(). If openStream returns FileNotFoundException it continues looking, but if openStream returns IOException it assumes something is wrong with the resource, stops looking and throws an exception. This works fine in a non OSGi environment, and also inside equinox, however it does not work inside Felix. Felix throws a IOException with the message: "Resource does not exist" instead of a FileNotFoundException. Compare the stack traces:
Felix: java.io.IOException: Resource does not exist: bundle://93.0:1/resource/myresource.stg at org.apache.felix.framework.URLHandlersBundleURLConnection.<init>(URLHandlersBundleURLConnection.java:131) at org.apache.felix.framework.URLHandlersBundleStreamHandler.openConnection(URLHandlersBundleStreamHandler.java:64) at java.net.URL.openConnection(URL.java:945) at java.net.URL.openStream(URL.java:1010) Equinox: java.io.FileNotFoundException: /resource/myresource.stg at org.eclipse.osgi.framework.internal.protocol.bundleresource.Handler.findBundleEntry(Handler.java:51) at org.eclipse.osgi.framework.internal.core.BundleResourceHandler.openConnection(BundleResourceHandler.java:175) at java.net.URL.openConnection(URL.java:945) at java.net.URL.openStream(URL.java:1010) Shouldn't the appropriate exception be FileNotFoundException ?
