Sahoo commented on FELIX-682:
-----------------------------
No, OSGi does not specify Implementation-Version header, but Java spec does.
See:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Package.html
Since the classloader that creates the Package in question is a Felix class
loader (org.apache.felix.framework.ContentClassLoader), it must create the
package with metadata as specified by user in manifest file unless the OSGi
spec mandates that java.lang.Package class can't be used in OSGi environment.
> Package.getImplementationVersion returns null for package loaded by Felix

> Even though MANIFEST.MF has proper entry for Implementation-Version,
> Package.getImplementationVersion() returns null. A reproducible test case is
> attached. It is described below:
> public class Foo implements BundleActivator {
> public void start(BundleContext context) throws Exception {
> Package p = getClass().getPackage();
> System.out.println(p);
> System.out.println(p.getImplementationVersion());
> }
> }
> The headers for this bundle are:
> osgi-test1 (10)
