butthough it does compile correctly I get an overflow error :
even without doing anything to this list !

You should reply to the same thread instead of starting a new one on the
First of all, there is no java.io in the code you posted, so the posted
code pretty certainly is not "probably ... the problem", since the error
clearly comes from a java.io.Writer. You should conclude from the error
message that code involved with a Writer is at fault, not that completely
unrelated code is involved.
Secondly, your reassignment of "myList" to the result of the method call
is redundant; it already points to the same list anyway.
Thirdly, it looks like what you need is a Set, not a List. Consequently,
fourthly, you should not name a variable ("classnamevalueslist") with its
implementation as part of the name. What sense does it make to declare
And isn't everything a "value"? Putting "value" in the name provides no
You should name the variable (using conventional camelCase) "classNames"
or something like that. Then you can change from Set to List to whatever
without having to rename everything.
Why a Set and not a List? Check out the Javadocs for those interfaces.
Speaking of interfaces,
fifthly, usually you should declare a variable with the interface type,
and instantiate it with the concrete type, as:
Set<String> classNames = new HashSet<String> ();
Unless you absolutely require the characteristics of a particular
implementation, this idiom provides more flexibility for plugin changes
(e.g., to a TreeSet).
Finally, to answer your main question we would need to see the code that
was actually involved in the error. On the face of it, something is
writing the results of a recursive method that has no termination
values ; now it workd neatly.
I should have put some more thoughts on my probem before posting.
