[jira] Created: (SM-1847) Executor service silently swallows any
Errors being thrown from Runnable task
Executor service silently swallows any Errors being thrown from Runnable task
-----------------------------------------------------------------------------
Key: SM-1847
URL: https://issues.apache.org/activemq/browse/SM-1847
Project: ServiceMix
Issue Type: Bug
Components: servicemix-utils
Affects Versions: 3.3, 3.2.3
Reporter: Gert Vanthienen
When an Error is thrown from within a Runnable submitted to the Executor service, the Error is silently ignored and there's even no log message for it.
An example (i.e. the way I found out about this):
If you write a custom FTP marshaler that used JAXB 2.1 and then run it on an early JDK 1.6 machine will give you a LinkageError. However, the Error is thrown from the marshaler operation in the processFile() method, but is never caught anywhere in the poller code (catches Exceptions but no Errors). In the end, the threadpool executor kills the thread but there's no trace of the Error
I would suggest implementing a generic catch-log-and-rethrow-Throwable in the servicemix-utils ExecutorImpl to make sure we at least have some log entry to show the exceptions/errors

Jean-Baptiste Onofré commented on SM-1847:
------------------------------------------
I will create an inner class into ExcecutorImpl that implements Runnable. This class will be responsible of exceptions catch and log.
