Heh, no problem :) , a native English speaker might be able to point them out better, but some of the sentences are a bit awkward, for example the beginning:
"Before a while a new major version of the well known log4j logging framework was released"
Starting your sentence with "Before" is awkward, because I'm expecting another language construction (for example "Before log4j was released, X happened"), I would have phrased it "It's been a while since"...
There are other phrasing constructs that signal that you're not a native English speaker (neither am I, so maybe that's why I might get confused by your phrasing).
Sorry to nitpick, the main point was talking about log4j :) , I've already recommended trying it out to the Java developers in my company :) - they mentioned that they're currently using logback, but that the improvements in log4j sound very promising.
Logback has been developed by the same guy who wrote log4j 1.x. He left and log4j 1 was not maintained a long time. But before a good while a few others have teamed up to bring the project back to life. With log4j 2 we have looked closely at other frameworks, including logback, and tried to make things better. Actually we have found a few things which we consider better. Still you need to consider log4j 2.0 is a young framework and in beta. That said, we are always glad about feedback. You and your developers are invited to join us on our mailing list and tell us what you think - good or bad. Thanks again for your interest (and bearing with my english)
