Yesterday I decided to migrate to wicket-1.4-m3 an after migrating my sources files to use Generic and compiling properly, I experience the following issue deploying the application :

I looked into FileChannelPool source file and the error seems to come with the current line in the class constructor when logging:

log.debug("Starting file channel pool with capacity of " + capacity + " channels");

thanks for your help
