    Versions used: Hudson 1.252 (installed debian package, run as application and not within tomcat), Violations Plugin 0.7.1, Java JDK 1.5.0_15 Since quite some time now (weeks?) we use the violations plugin 0.7.1 within Hudson. Though once it worked (unclear since when) correctly, with the latest version of the violations plugin (v0.7.1) we get the following error when accessing an URL like: (a) http://hudson-server:8080/job/HadesSite/90/violations/ (b) http://hudson-server:8080/job/HadesSite/violations/ And some of the violation trend-graphs are not created: ad (a): for a specific build, the violation-graph IS created for single modules, but the aggregated graph is not created ad (b): for that link, there are NO violation-graphs at all (only the surrogate "empty" icon indicating, that there's no image to load) Can somebody help what is wrong here? Strange is, that it once worked. I guess (but only guess), that maybe the reports to be aggregrated have a changed and now inconsistent data format. We use the following hudson plugins in the site report build process: checkstyle plugin 1.15, pmd (+cpd) plugin 1.15, findbugs plugin 2.18 The hudson.log shows the following errors when choosing one of the above URLs (for our internal project HadesSite): [webapp 2008/09/23 11:52:10] - Error while serving http://dombuilder.schlund.de:8080/job/NexDomSite/violations/graph java.lang.reflect.InvocationTargetException at sun.reflect.GeneratedMethodAccessor342.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.kohsuke.stapler.Function$InstanceFunction.invoke(Function.java:103) at org.kohsuke.stapler.Function.bindAndinvoke(Function.java:57) at org.kohsuke.stapler.MetaClass$1.doDispatch(MetaClass.java:75) at org.kohsuke.stapler.NameBasedDispatcher.dispatch(NameBasedDispatcher.java:30) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:440) at org.kohsuke.stapler.MetaClass$15.dispatch(MetaClass.java:384) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:440) at org.kohsuke.stapler.MetaClass$9.doDispatch(MetaClass.java:263) at org.kohsuke.stapler.NameBasedDispatcher.dispatch(NameBasedDispatcher.java:30) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:440) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:361) at org.kohsuke.stapler.Stapler.service(Stapler.java:121) at javax.servlet.http.HttpServlet.service(HttpServlet.java:45) at winstone.ServletConfiguration.execute(ServletConfiguration.java:249) at winstone.RequestDispatcher.forward(RequestDispatcher.java:335) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:378) at hudson.util.PluginServletFilter$1.doFilter(PluginServletFilter.java:61) at hudson.util.PluginServletFilter.doFilter(PluginServletFilter.java:53) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at hudson.security.HudsonFilter.doFilter(HudsonFilter.java:88) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at winstone.RequestDispatcher.forward(RequestDispatcher.java:333) at winstone.RequestHandlerThread.processRequest(RequestHandlerThread.java:244) at winstone.RequestHandlerThread.run(RequestHandlerThread.java:150) at java.lang.Thread.run(Thread.java:595) Caused by: java.lang.NullPointerException [Winstone 2008/09/23 11:52:10] - Untrapped Error in Servlet java.lang.NullPointerException javax.servlet.ServletException at org.kohsuke.stapler.Stapler.invoke(Stapler.java:449) at org.kohsuke.stapler.MetaClass$15.dispatch(MetaClass.java:384) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:440) at org.kohsuke.stapler.MetaClass$9.doDispatch(MetaClass.java:263) at org.kohsuke.stapler.NameBasedDispatcher.dispatch(NameBasedDispatcher.java:30) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:440) at org.kohsuke.stapler.Stapler.invoke(Stapler.java:361) at org.kohsuke.stapler.Stapler.service(Stapler.java:121) at javax.servlet.http.HttpServlet.service(HttpServlet.java:45) at winstone.ServletConfiguration.execute(ServletConfiguration.java:249) at winstone.RequestDispatcher.forward(RequestDispatcher.java:335) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:378) at hudson.util.PluginServletFilter$1.doFilter(PluginServletFilter.java:61) at hudson.util.PluginServletFilter.doFilter(PluginServletFilter.java:53) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at hudson.security.HudsonFilter.doFilter(HudsonFilter.java:88) at winstone.FilterConfiguration.execute(FilterConfiguration.java:195) at winstone.RequestDispatcher.doFilter(RequestDispatcher.java:368) at winstone.RequestDispatcher.forward(RequestDispatcher.java:333) at winstone.RequestHandlerThread.processRequest(RequestHandlerThread.java:244) at winstone.RequestHandlerThread.run(RequestHandlerThread.java:150) at java.lang.Thread.run(Thread.java:595) #--------------- If you need more info to investigate, please let me know.

    Kirk True <ktrue@linkedin.com> wrote to mailing list: -- Hi all, We're running 1.198 and are trying to switch over to matrix-based security, but we're seeing some issues. I have defined a user that has all permissions (job create, configure, etc.) *except* Administer (under the "Overall" section). When that user views an existing job configuration screen, we see the following error under the "Repository URL" and "Repository browser" URL sections: Status Code: 403 Exception: Stacktrace: (none) Attempting to save the configuration as this user doesn't work either as we get the same 403 error on a screen all by itself. However, nothing seems to show up in the logs. When that user attempts to create a new job, we get a new job configuration screen (which has the same ‘403’ error right under the new job name), but this time I see some output in the logs: [webapp
