### With Immutant
Using the advanced features of the `info` middleware with WildFly/Immutant
requires a tweek, since JBoss modules prevent modifications to `AppClassLoader`
(usually the highest modifiable classloader) from being seen by application
code. To work around this, run the following code from within your
WildFly/Immutant container to mark that classloader as unmodifiable, and cause
the lower level `clojure.lang.DynamicClassLoader` to be used instead. This code
must execute prior to loading the `cider-nrepl` middleware.
### With JBoss AS/JBoss EAP/WildFly

Using the advanced features of the `info` middleware with one of the
JBoss application servers requires a tweak, since JBoss modules
prevent modifications to `AppClassLoader` (usually the highest
modifiable classloader) from being seen by application code. To work
around this, run the following code from within your application
to mark that classloader as unmodifiable, and cause the lower level
`clojure.lang.DynamicClassLoader` to be used instead. This code must
execute prior to loading the `cider-nrepl` middleware. Note that this
is only if you are deploying a standard WAR file to the application
server directly. If you are using [Immutant](http://immutant.org/)
(1.x or 2.x), you won't need to do this.
