http://issues.apache.org/bugzilla/show_bug.cgi?id=30548 NPE in oata.Project when executing emma task from netbeans. ------- Additional Comments From [EMAIL PROTECTED] 2004-08-15 05:51 ------- Did the following: - upgraded Ant in Netbeans to 1.6.2. - patched the getThreadMethod() again, to read: 2020 public Task getThreadTask(Thread thread) { 2021 try 2022 { 2023 Object task = threadTasks.get(thread); 2024 if (task == null) { 2025 ThreadGroup group = thread.getThreadGroup(); 2026 while (task == null && group != null) { 2027 task = threadGroupTasks.get(group); 2028 group = group.getParent(); 2029 } 2030 } 2031 return (Task) task; 2032 } 2033 catch (NullPointerException npe) 2034 { 2035 System.out.println("NPE in getThreadTask!!"); 2036 npe.printStackTrace(); 2037 System.out.println("Parameter thread: " + thread); 2038 System.out.println("Map threadTasks: " + threadTasks); 2039 System.out.println("Map threadGroupTasks: " + threadGroupTasks); 2040 //System.out.println("task: " + task); 2041 System.out.println("this.getClass().getName()" + this.getClass().getName()); 2042 System.out.println("this" + this); 2043 return null; 2044 } 2045 } Now got as a response: coverage: NPE in getThreadTask!!

Currently I have no Idea how this should happen, if the only setting of this variable in the whole sourcetree seems to be: 165 /** Records the latest task to be executed on a thread (Thread to Task). */ 166 private Hashtable threadTasks = new Hashtable(); Ideas? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
