Classloader problem limit LogSystem creation

           Summary: Classloader problem limit LogSystem creation
           Product: Velocity
           Version: 1.2
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Source
        AssignedTo: velocity-dev@jakarta.apache.org
        ReportedBy: uri.agassi@cash-u.com


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.
