Incorrect class loading due to implicit boot delegation
-------------------------------------------------------

                 Key: FELIX-3074
                 URL: https://issues.apache.org/jira/browse/FELIX-3074
             Project: Felix
          Issue Type: Bug
          Components: Framework
    Affects Versions: framework-3.0.8
            Reporter: Sahoo
            Priority: Critical


While analysing some inexplicable errors in my test environment, I came across this bug. The thread stack below causes a class from parent loader to be loaded when I expected it not to.

As per the logic in ModuleImpl.java, isClassExternal(java.util.ServiceLoader$LazyIterator.class) return true, so it boot delegates.
