There's your first issue.  You do not need to use JUL-to-SLF4J in order to log JUL messages in AS 7.  Our stub version of this library actually does nothing and is only there to prevent errors in existing code.

If you have both a logging.properties and a log4j.properties, I believe the log4j.properties will be ignored.  You can only have one logging configuration file per deployment, and that configuration applies to all logging APIs, including slf4j, JUL, log4j, etc.  AS automatically unifies all log frameworks.

You do not need any slf4j JARs as AS7 already provides them all.  Any slf4j JAR you do provide should be ignored, though I'd leave them out just to be safe.
