No, it's in the org.eclipse.core.runtime package but it is actually 
defined in the equinox.registry bundle.  ContributorFactorySimple is 
also in the equinox.registry bundle.

Also, check in the thread titled "Using Extension Registry without OSGi" 
in eclipse.technology.equinox.  It looks like you don't even need the 
org.eclipse.osgi bundle, but can reduce the size needed by using the 
supplemental one.

It can be done completely with the 3 jars mentioned in this thread and a 
java app:

masterToken = new Object();
registry = RegistryFactory.createRegistry(new RegistryStrategy(null, 
null), masterToken, null);

Then for each plugin.xml you need to check:

InputStream pluginXmlInput = ...;
String pluginXmlId = ...;
ResourceBundle pluginXmlResources = null; // or dig out the correct one
registry.addContribution(pluginXmlInput, 
ContributorFactorySimple.createContributor(pluginXmlId), false, 
pluginXmlId, pluginXmlResources, masterToken);

Later,
