[seam-issues] [JBoss JIRA] Commented: (SEAMSERVLET-19) Catch integration swallows unhandled runtime exceptions

Catch integration swallows unhandled runtime exceptions ------------------------------------------------------- Key: SEAMSERVLET-19 URL: https://issues.jboss.org/browse/SEAMSERVLET-19 Project: Seam Servlet Issue Type: Bug Components: Catch integration Affects Versions: 3.0.0.Alpha2 Reporter: Jozef Hartinger Priority: Critical Fix For: 3.0.0.Alpha3 The spec says: If the servlet that is the target of a request dispatcher throws a runtime exception or a checked exception of type ServletException or IOException, it should be propagated to the calling servlet. All other exceptions should be wrapped as ServletExceptions and the root cause of the exception set to the original exception, as it should not be propagated. CatchExceptionFilter contains this code: if (!catchEvent.isHandled()) { if (e instanceof ServletException) { throw (ServletException) e; } else if (e instanceof IOException) { throw (IOException) e; } } which takes care of ServletExceptions and IOExceptions, however, runtime exceptions are swallowed.
