>             Project: Velocity
>          Issue Type: Bug
>          Components: Engine
>    Affects Versions: 1.2
>         Environment: Operating System: All
> Platform: PC
>            Reporter: Uri Agassi

> When you run velocity using external-dir ClassLoader (by putting it in the -
> Djava.ext.dir property in the java command line), you cannot use a class for 
> the LogSystem that is in the regular classpath (a NoClassDefFoundError will be 
> issued).
> This will happen every time that the velocity package is on a ClassLoader that 
> is higher in the hierarchy than the LogSystem class, due to the behaviour of 
> the ClassLoader.
> To resolve this, the Velocity.init should have an overloading with a 
> ClassLoader as parameter, and it should be used in every Class.forName in the 
> code.
