Re: [mylyn-integrators] Retrieving Bugs from https://bugzilla.redhat.com 
Hi Jerry,
Frank Becker has investigated and it appears to be due to the sure size of RedHat's bugzilla configuration file. Resolution is currently being tracked on the following bug report:
239435: [patch] trying to synchronize with http://partner-bugzilla.redhat.com/ RedHat 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=239435
Consider adding yourself to the cc and voting. If you could through your set code on that bug as well that would be great. 

Thanks,

-Rob

Hi, all...
Can anybody give me a hint as to why the following doesn't work? It goes away for a long period of time before coming back with:

The code apes the Bugzilla headless Mylyn API sample pretty closely and actually works without incident against a few other repositories like the Bugzilla landfill 3.0 test repository and the bugs.eclipse.org <http://bugs.eclipse.org> 2.18 test repository. It's only attempting to retrieve a single bug so it puzzles me that something is going memory crazy down within...
public void test_PoC_Bugzilla_fetch_single_bug_on_redhat() throws Exception 
    {
        final String URL = "https://bugzilla.redhat.com";;
        final String BUG_ID = "6740";

new TaskRepository(BugzillaCorePlugin.CONNECTOR_KIND, 
                                           URL);

        AuthenticationCredentials credentials =
new AuthenticationCredentials("jerrykuch@xxxxxxxxx <mailto:jerrykuch@xxxxxxxxx>", 
                                                      "wawawa");
        repository.setCredentials(AuthenticationType.REPOSITORY,
                                  credentials,
                                  false);

        BugzillaRepositoryConnector connector =
new BugzillaRepositoryConnector(); 

        try
        {
            // Get a bug report from Bugzilla...
TaskData taskData = connector.getTaskData(repository, BUG_ID, null); 

            // Get the information on the bug report...
            ITaskMapping taskMapping = connector.getTaskMapping(taskData);

            // Is the task information what we expected it to be?
System.out.println("Summary: " + taskMapping.getSummary());
System.out.println("Priority: " + taskMapping.getPriority()); 

            // Try to access bug report data via attributes...
            TaskAttribute descriptionAttribute =
taskData.getRoot().getMappedAttribute(TaskAttribute.COMPONENT); 
            System.out.println("Component:   "
                                + descriptionAttribute.getValue());

            // ...or by Bugzilla keys

BugzillaAttribute.BUG_SEVERITY.getKey() 
                                                               );
System.out.println("Severity: " + severityAttribute.getValue()); 
        }
        catch (CoreException e)
        {
            throw new Exception(e);
        }
        finally
        {
/* This is worth remembering, but really shouldn't be done here since it shuts down a common global piece of Mylyn infrastructure 
               which will make subsequent tests fail!

               CommonsNetPlugin.getExecutorService().shutdown();
            */
            assertTrue(true);   // Don't complain about empty finally!
