------------------------------------

             Summary: One reference can be unset more then once and will cause IllegalStateException in Framework
                 Key: FELIX-6726
                 URL: https://issues.apache.org/jira/browse/FELIX-6726
             Project: Felix
          Issue Type: Bug
          Components: Declarative Services (SCR)
    Affects Versions: scr-2.2.12
            Reporter: Jürgen Albert


We have a Component Foo registered under Interface A and B. A also extends B.

A Prototype Component Bar references the Service under its interface A.

When the prototype instance is cleaned up, the DependencyManager of SCR calls unget for the instance Foo 2 times, because it thinks that the one Instance are 2 RefPairs. One under the Interface A and one under B. Unget is now called by the DependencyManager 2 times but the Framework only knows about one usage. In this case the IllegalState Exception is thrown.

The relevant parts of the Stacktrace:
