We've recently discovered bug related to SPARQL update an latest sesame.
It is not possible to evaluate query like this one:
See https://openrdf.atlassian.net/browse/SES-2063. This was fixed in Sesame 2.7.13, but still occur in bigdata. Maybe it is related to the way in which bigdata uses sesame. (It could also be that the fix in openrdf was not made to the grammar such that recompilation from the jjt files did not preserve the fix.)
A related QUADS DATA issue is BLZG-1097.
