State doesn't return all plugin versions [message #644627]

I am using org.eclipse.osgi.service.resolver.State to get all versions of a Plugin installed i.e. latest version and older versions.

The code I'm using is:


 PlatformAdmin platformAdmin = Platform.getPlatformAdmin();
 State state = platformAdmin.getState();
 BundleDescription[] bundles = state.getBundles("com.my.plugin");

The State.getBundles(String symbolicName) is supposed to return all bundle descriptions with the given bundle symbolic name.

However, it is only returning the latest version 2.0.0. Older version 1.0.0 is not picked up.

Is it a singleton bundle?

Yes I had to make the plugin a singleton because it defines an extension.

The plugin's extension basically defines a path to a resource (a file within the plugin).

The plugin does not contain any code.

If it's a singleton, then the system only allows one version (and you should only get back on state). This sounds like it is working correctly.
