Description

Currently when a resource is not found inside a bundle, an IOException is thrown with the message: "Resource does not exist" . It would be more useful to throw instead a FileNotFound exception. This behavior happens outside OSGi and also in Equinox. For example look the stack trace in 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)

This small fix would improve compatibility with 3rd parties that rely on this behavior, and also improve compatibility with the behavior in equinox.
