> I would like to suggest a patch improving performance of util.logging.Logger.
> Summary of changes:
> 1. Frequently (on each logging call) used internalIsLoggable method became not synchronized
and not  "walking" through parents if a logger should inherit a parent level. As setLevel
occures much rarely than log call it is preferable to inherit a parent level when setting
a parent and when changing a parent. internalIsLoggable uses int value of log level to avoid
extra call to Level.intValue() method.
> 2. Main log method uses getHandlers returning array of handlers on each logging call.
So, handlers.toArray(new Handler[0]) has been changed to handlers.toArray(new Handler[handlers.size()])
to avoid excessive creation of the array. It is much faster.
