The ASF has issued new guidelines for source file header at http://www.apache.org/legal/src- headers.html that are required for all releases after November 1st. This will require touching all or almost all of the source files for both the trunk and 1.2 branches.
Initial commit on log4j 1.2 branch in rev 511036.
Updated selected file on trunk (aka log4j 1.3) in rev 527394 in preparation for backporting plugins, rule- based filtering and receivers for Chainsaw on log4j 1.2 effort.
Fixed in log4j 1.2. Walking away from log4j 1.3.
