[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-2714) Detect swallowed exceptions

Detect swallowed exceptions --------------------------- Key: JBSEAM-2714 URL: https://jira.jboss.org/jira/browse/JBSEAM-2714 Project: Seam Issue Type: Feature Request Components: Exception Handling Reporter: Matt Drees Priority: Minor Sometimes exceptions are swallowed by frameworks out of Seam's control (Facelets debug component, for example does this; see http://www.seamframework.org/Community/FetchingDataLazilyOnANewPage#comme...). However, a rollback may be triggered by the throwing of such an exception, due to the RollbackInterceptor. Because the exception is swallowed, the developer has no immediate indication that an error has occurred, yet the persistence context will be cleared. It's a very frustrating experience, trust me. Could Seam use an interceptor to note when a (non-application) exception is thrown by a Seam component, and if it is not eventually handled by Seam's exception handler at the end of the request, trigger a warning & a stacktrace in the log?
