I'm hunting that bug too ;-)
My observation until now is that:
a) SitemapLanguage#createNodeBuilder creates the CallNodeBuilder
b) it seems (during my debugging) there is only one CallNodeBuilder in
the system (even though it is not marked ThreadSafe as other
NodeBuilders)
c) in CallNodeBuilder#buildNode the member variable node will be
overwritten each time that method is called (and it is called for
each <map:call .../> element)
I don't know what a NodeBuilder should do in its buildNode method but I
think there might be the problem. Later in the processings the linkNode
method on the CallNodeBuilder gets called where the interpreter is set
on the node. But because of c) only one instance gets the interpreter
and if one of the other Nodes created gets processed in a pipeline we'll
have a NPE.
Hope that helps other bug hunters a bid as I don't now how to proceed
ATM (is there a problem with non ThreadSave components?)
The problem is that the builder objects mustn't be threadsafe but the container
always returns the same instance. Though I have no idea how/where to change this ...
