/*
 We can't use JString or any other J2K classes, since we are not sure,
 where the error occured and so, we can only rely on ourself !
 Hoping that this class works well... =)

 We are using a single forward link-list of " void function( ARG ) ",
 the function must be public and static inside or outside a class,
 even if an object of that class was not build anywhere.
 It might look "weird" but it's VERY convenient!  =]
