Same as above, this can whole work behind log4j2 can only be in 4.0.0 if we

Review Comment:
Unfortunately we can't keep this method on trunk branch, because this method
directly takes commons logging Log reference :(
And since this class is IA.Public, this change can only be taken up in trunk
branch only and not on branch-3.3 for now.
We can move forward with log4j2 only on 4.0.0 release (something similar to
hbase). FYI @Apache9
