@ -222,7 +222,7 @@ incorrectly using them in multi-threaded and multi-classloader environments. You
should always consider wrapping a `ThreadLocal` in some other class and never directly use
the `ThreadLocal` itself (except in the wrapper class). Also, you should
always remember to correctly set and unset (where the latter simply involves a call to
`ThreadLocal.set(null)`) the resource local to the thread. Unsetting should be done in
`ThreadLocal.remove()`) the resource local to the thread. Unsetting should be done in
any case, since not unsetting it might result in problematic behavior. Spring's
`ThreadLocal` support does this for you and should always be considered in favor of using
`ThreadLocal` instances without other proper handling code.
