Uncaught exceptions in main methods are being obscured
------------------------------------------------------
Key: DAEMON-165
URL: https://issues.apache.org/jira/browse/DAEMON-165
Project: Commons Daemon
Issue Type: Bug
Components: Procrun
Affects Versions: 1.0.2
Environment: Procrun running on windows with any java release
Reporter: Antony Scerri
Inside the__apxJavaWorkerThread method in javajni.c the following line just
after the call to execute the main method:
JVM_EXCEPTION_CLEAR(lpJava);
is making any uncaught exception in the main method simply disappear. This can
make diagnoising startup and/or shutdown issues in applications over which you
have no direct control (ie third party apps for which you dont have
sourcecode). I had this where a classpath error was causing some issues and
later some other exceptions, all were completely hidden until I removed this
line.
Two solutions I believe are possible.
1) Simply remove this line, the VM will then handle the exception by outputting
it to standard error in which case it will appear in the service stderr log
file.
2) Check for and then obtain any exception and log appropriately
The second would give greater control to procrun and be more prominant in the
main log rather than the stderr logs.
