---------------------------------------
If it helps, at all, I'm seeing exactly the same issue on Tomcat 6.0.26/Windows - however with ch.qos.logback.classic.util.CopyOnInheritThreadLocal instead of org.slf4j.impl.CopyOnInheritThreadLocal. To take a couple of examples ...
SEVERE: A web application created a ThreadLocal with key of type [null] (value [ch.qos.logback.core.UnsynchronizedAppenderBase$1 at ba3671]) and a value of type [java.lang.Boolean] (value [false]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.
SEVERE: A web application created a ThreadLocal with key of type [ch.qos.logback.classic.util.CopyOnInheritThreadLocal] (value [ch.qos.logback.classic.util.CopyOnInheritThreadLocal at 12704b3]) and a value of type [java.util.HashMap] (value [{callid=e4ac4593-1f59-4801-9671-078eb6e5c86b}]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.
