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. [1] <https://bugs.eclipse.org/bugs/show_bug.cgi?id=488006>
Mat, would you please investigate this one?
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
