http://issues.apache.org/bugzilla/show_bug.cgi?id=39393 ------- Additional Comments From [EMAIL PROTECTED] 2006-05-03 07:26 ------- It is difficult to explain the multi-threading issue. But I'm going to try! It's my understanding that exception was occured under the following procedure. 1) Both thread-A and thread-B have reached at line 663 of ValidatorAction. Because this block doesn't be protected by synchronization. 657: private void loadParameterClasses(ClassLoader loader) 658: throws ValidatorException { 659: 660: if (this.parameterClasses != null) { 661: return; 662: } 663: 664: this.parameterClasses = new Class[this.methodParameterList.size()]; 2) thread-A has reached at line 621 of ValidatorAction. 617: private void loadValidationMethod() throws ValidatorException { 618: if (this.validationMethod != null) { 619: return; 620: } 621: 622: try { 623: this.validationMethod = 624: this.validationClass.getMethod(this.method, this.parameterClasses); 625: 626: } catch (NoSuchMethodException e) { 627: throw new ValidatorException(e.getMessage()); 628: } 3) thread-B has executed line 664. Then, parameterClasses variable has been initialized. 4) thread-A has executed line 624. Then, NoSuchMethodException was occured. After that, ValidatorException was throwed at line 627. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
