Hey,
I'm trying to write an in-memory Dataset (guesstimate: a few hundred
thousand quads) like this:
RDFDataMgr.write(entityStream, dataset, lang);
What I get is:
java.lang.StackOverflowError

Any ideas? Is Jena running out of memory?
There is either a very long chain of IteratorCons or an IteratorCons
object points to itself as the next IteratorCons.
The full trace should tell you where the first IteratorCons.hasNext call
is from.
The NQuads writer does not use IteratorCons so it is something in the
dataset setup. NQuads writing uses an iterator from
DatasetGraph.find(?,?,?,?).
