   There are several loaders that return the same ID when looking up providers for 'org.mule.runtime.module.artifact.ExtensionModelLoader'. Full error list:
   ID [some-id] is being returned by the following classes [org.foo.FooLoader, org.bar.BarLoader]
   ID [another-id] is being returned by the following classes [org.foo2.FooLoader2, org.bar2.BarLoader2]
 

Specified by:

start in interface org.mule.runtime.api.lifecycle.Startable

Throws:

IllegalStateException - if there are loaders with repeated IDs.
