-------------------------------------
Summary: HttpService: Cannot unregister
javaxwrappers.ServletWrapper
Key: FELIX-6745
URL: https://issues.apache.org/jira/browse/FELIX-6745
Project: Felix
Issue Type: Bug
Components: HTTP Service
Affects Versions: http.jetty12-1.0.19
Reporter: Andreas Lemmer
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#getServlet}} where the CCE
happens).
