Pierre De Rop reassigned FELIX-5436:
------------------------------------
Assignee: Pierre De Rop
> Log message 'callback not found on component instances' incorrectly shown if
> exception occurs during calling of callback method
> -------------------------------------------------------------------------------------------------------------------------------
>
> Key: FELIX-5436
> URL: https://issues.apache.org/jira/browse/FELIX-5436
> Project: Felix
> Issue Type: Bug
> Components: Dependency Manager
> Affects Versions: org.apache.felix.dependencymanager-r8
> Reporter: Jeroen Daanen
> Assignee: Pierre De Rop
> Priority: Minor
>
> In the method ComponentImpl.invokeCallbackMethod(Object[], String,
> Class<?>[][], Object[][], boolean) a message is logged when an exception
> occurs during call of the callback method, because in that case the
> 'callbackFound' variable is not set.
> This is confusing when reading error log.
> Suggestion for code change:
> {code}
> public void invokeCallbackMethod(Object[] instances, String methodName,
> Class<?>[][] signatures,
> Object[][] parameters, boolean logIfNotFound) {
> boolean callbackFound = false;
> boolean exceptionOccurredInCallback = false;
> for (int i = 0; i < instances.length; i++) {
> try {
> InvocationUtil.invokeCallbackMethod(instances[i], methodName,
> signatures, parameters);
> callbackFound |= true;
> }
> catch (NoSuchMethodException e) {
> // if the method does not exist, ignore it
> }
> catch (InvocationTargetException e) {
> // the method itself threw an exception, log that
> m_logger.log(Logger.LOG_ERROR, "Invocation of '" + methodName
> + "' failed.", e.getCause());
> exceptionOccurredInCallback = true;
> }
> catch (Throwable e) {
> m_logger.log(Logger.LOG_ERROR, "Could not invoke '" +
> methodName + "'.", e);
> exceptionOccurredInCallback = true;
> }
> }
>
> // If the callback is not found, we don't log if the method is on an
> AbstractDecorator.
> // (Aspect or Adapter are not interested in user dependency
> callbacks)
> if (logIfNotFound && ! exceptionOccurredInCallback && ! callbackFound
> && ! (getInstance() instanceof AbstractDecorator)) {
> if (m_logger == null) {
> System.out.println("\"" + methodName + "\" callback not found
> on component instances "
> + Arrays.toString(instances));
> } else {
> m_logger.log(LogService.LOG_ERROR, "\"" + methodName + "\"
> callback not found on component instances "
> + Arrays.toString(instances));
> }
> }
> }
> {code}
