> UIMA Logger setLevel(Level) only partially works. It changes the level 
> associated with the logger, but its not changing a level in any of its 
> handlers (like ConsoleHandler). So the code,
> logger.setLevel(Level.FINEST);
> if ( logger.isLoggable(Level.FINEST) ) {
> } 
> works fine. What does *not* work is the following:
> logger.log(Level.FINEST, aMessage);
> The only workaround for this is to use, now deprecated, 
> setOutputStream(System.out). 
> Possible fix could be Uima Logger API extension to return an array of 
> handlers associated with a logger. The client application can than decide 
> appropriate log levels for each of the handlers programatically. 
> Another fix for this is to change setLevel(Level) implementation, and apply 
> the new setting across all the handlers associated with the logger. This is 
> less flexible than the first but perhaps more convenient.
> Any thoughts?
