https://bugzilla.redhat.com/show_bug.cgi?id=1309687 Bug ID: 1309687 Summary: Undeclared uses constraints of Apache HttpComponent bundle cause linkage error at runtime Product: Fedora Version: 23 Component: eclipse Assignee: akurtako(a)redhat.com Reporter: andreas.sewe(a)codetrails.com QA Contact: extras-qa(a)fedoraproject.org CC: akurtako(a)redhat.com, andjrobins(a)gmail.com, eclipse-sig(a)lists.fedoraproject.org, jerboaa(a)gmail.com, krzysztof.daniel(a)gmail.com, mat.booth(a)redhat.com, rgrunber(a)redhat.com External Bug ID: Eclipse Project 488006 Description of problem: Version-Release number of selected component (if applicable): 1:4.5.1-1.fc23 How reproducible: Always. Steps to Reproduce: 1. Install "Eclipse" (version 1:4.5.1-1.fc23) from "Software" 2. Start Eclipse 3. Help > Install New Software "Code Recommenders for Java Developers" from pre-configured update site <http://download.eclipse.org/releases/mars> 4. Restart Eclipse 5. Try to open Code Recommenders "Model Repositories" view (it is not there, as bundles for Code Recommenders" are not resolved. This is the *first* problem 6. Start Eclipse with "-clean" option 7. Try to open Code Recommenders "Model Repositories" view again Actual results: An error dialog appear: loader constraint violation in interface itable initialization: when resolving method "org.apache.http.message.AbstractHttpMessage.getHeaders(Ljava/lang/String;)[Lorg/apache/http/Header;" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, org/apache/http/client/methods/AbstractExecutionAwareRequest, and the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for interface org/apache/http/HttpMessage have different Class objects for the type [Lorg/apache/http/Header; used in the signature Expected results: The "Model Repositories" view opens and (in the background) a download of the model repository index for is started. Once finished, the view shows 4.5.76 known coordinates for the "mars" model repository. Additional info: More details on what the OSGi bundle headers look like can be found in the bug I filled with the Eclipse Orbit project [1], although they are not the ones who distribute bundles with faulty Export-Package headers (i.e., headers without uses constraints). FWIW, the symptoms seem to be very similar to those of Bug 807044.
