Description

When I am debugging Jena-based code and mouse-over a dataset variable, the system basically hangs. It seems that the toString() method of DatasetGraphBase is producing a complete rendering of the whole dataset using WriterGraph.output(out, this, null). And our datasets typically contain thousands of named graphs, some of which are quite large.

This is handled much better in places such as GraphBase.toString, which terminates after a certain number of triples.
