Alex Earl added a comment - 2013-10-10 19:20 Looks like its in this code (which I think is different from the original submitter of the issue) while (upc != null ) { // UpstreamCause.getUpStreamProject() returns the full name, so use getItemByFullName AbstractProject<?, ?> p = (AbstractProject<?, ?>) Hudson.getInstance().getItemByFullName(upc.getUpstreamProject()); cur = p.getBuildByNumber(upc.getUpstreamBuild()); // line 535 upc = cur.getCause(Cause.UpstreamCause.class); } I guess p could be null
