It is just a historic reason.
To add another word,
dependency to junit and log4j is only test scope. not compile or runtime scope.
I can run "mvn test" with these old library. so, there are no problem.
The log4j1.4.x has many sub dependency but log4j1.2.x has no other sub dependency. Its' simple.
Also, junit4.8 is old. But spring-test-3.x need old junit4, so I use old one.
