Richard S. Hall commented on FELIX-1124:
----------------------------------------
Thomas, I created the following bundle activator:
public class Activator implements BundleActivator
{
public void start(final BundleContext context) throws Exception
{
getClass().getClassLoader().getResourceAsStream("does/not/exist.txt");
}
public void stop(BundleContext context)
{
}
}
When I run this in Felix I get:
-> ps
START LEVEL 1
ID State Level Name
[ 0] [Active ] [ 0] System Bundle (1.9.0.SNAPSHOT)
[ 1] [Active ] [ 1] Apache Felix Shell Service (1.3.0.SNAPSHOT)
[ 2] [Active ] [ 1] Apache Felix Shell TUI (1.3.0.SNAPSHOT)
[ 3] [Active ] [ 1] Apache Felix Bundle Repository (1.5.0.SNAPSHOT)
[ 5] [Installed ] [ 1] test.logger
-> start 5
DEBUG: WIRE: 5.0 -> org.osgi.framework -> 0
DEBUG: does/not/exist.txt
(org.apache.felix.moduleloader.ResourceNotFoundException: does/not/exist.txt)
->
I do not get a stack trace, which is what I would expect from the code for
Logger. Are you passing in a Logger instance to Felix when you construct it or
are you just using Felix' launcher? If the former, I would have to assume that
the passed in launcher is printing the stack trace.
Let me know if I am missing something.

> Key: FELIX-1124
> URL: https://issues.apache.org/jira/browse/FELIX-1124
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: felix-1.6.1, felix-1.8.0, felix-1.8.1
> Reporter: Thomas Diesler
>
> ModuleImpl logs stack traces for every resource that cannot be found. Often
> resources are optional or may be located at different locations.
> public URL getResourceByDelegation(String name)
> {
> try
> {
> return (URL) findClassOrResourceByDelegation(name, false);
> }
> catch (ClassNotFoundException ex)
> {
> // This should never be thrown because we are loading resources.
> }
> catch (ResourceNotFoundException ex)
> {
> m_logger.log(
> Logger.LOG_DEBUG,
> ex.getMessage(),
> ex);
> }
> return null;
> }
> Please consider a log message without stack trace and leave it to the client
> to be more verbose when appropriate.
> To log no message at all and simply return null would also be consistent with
> http://java.sun.com/javase/6/docs/api/java/lang/ClassLoader.html#getResource(java.lang.String)
