Hi,
I've just got a ConcurrentModificationException outputing jsonld, in the
following circumstance: trying to output the content of a given named graph of
a TDB store, twice at the same time (output called from a jersey servlet).
The problem exists in 3.1.1 and 3.1.0. Stacktraces below.
I don’t understand. Sorry to see this only now.
fps
StackTrace with 3.1.0:
GRAVE: Servlet.service() for servlet [Jersey Web Application] in context with
path [/rasse] threw exception [java.util.ConcurrentModificationException:
