Noooooo...
#set($newobject = $foo.class.forName("myclass").newInstance())
is just not a good way of doing this. It's error-prone, hard to read,
may not be supported in future versions of Velocity. Instead, create
an instance of the object and put it into the context before Velocity
is called with
context.put("newobject", new MyClass());
Note to Claude: I've got a new (simpler) Uberspector subclass that
addresses this. I'm going to integrate it into 1.5 during our
Hackathon in two weeks.

Do you mean :
"How to put a new instance of a class in the velocity context from
inside the vtl?"
Usually, you put classes in the context using java
(context.put("name",object)), or using toolbox.xml if you rely on the
VelocityTools subproject.
Now, if you really want to load a new instance of a class in the context
from inside the VTL, you have the following hack:
#set($newobject = $foo.class.forName("myclass").newInstance())
where $foo can be any existing reference.
But this is really not a very clean coding style... Also, the class you
load must have a default constructor (otherwise it is still possible but
more complex).
By the way, dev people, why is this issue only scheduled for 1.6? Will's
patch seems to be ready in
http://issues.apache.org/jira/browse/VELOCITY-179 and backward
compatible with proper default configuration value.
