Andreas Lemmer updated FELIX-6745:
----------------------------------
Description:
When (manually) registering an
{{org.apache.felix.http.javaxwrappers.ServletWrapper}} servlet at
{{{}org.osgi.service.http.HttpService{}}}, it cannot be unregistered anymore:
{{java.lang.ClassCastException: class (WrappedServlet) cannot be cast to class
org.apache.felix.http.jakartawrappers.ServletWrapper}}
{{at
org.apache.felix.http.base.internal.service.SharedHttpServiceImpl.getServlet(SharedHttpServiceImpl.java:117)}}
{{at
org.apache.felix.http.base.internal.service.SharedHttpServiceImpl.unregister(SharedHttpServiceImpl.java:100)}}
This is because registering the ServletWrapper actually registers the wrapped
servlet (see
{{{}org.apache.felix.http.jakartawrappers.ServletWrapper#getRegisteredServlet){}}},
but unregistering assumes that the registered servlet is an
{{org.apache.felix.http.jakartawrappers.ServletWrapper}} (see
{{{}org.apache.felix.http.base.internal.service.{}}}{{{}SharedHttpServiceImpl{}}}{{{}#getServlet{}}}
where the CCE happens).
