If you read the Javadoc, it should be fairly clear what's wrong. The
"toString()" method of a classifier returns a string representation of
its model (if the classifier generates one). The "toSource(String)"
method expects a classname as parameter. Using the string
representation of the tree as classname doesn't seem such a good idea
(it won't generate valid Java code either).
