Hi Bart,
Innl.netage.storetest.Reader
could you add this as a class static initializer at the beginning of the
class:
static { jenaSystem.init(); }
if that works, adding it to info.resc.pontypandy.store.StoreFactory
(assuming that's your code).
In general, especially if there might be multiple threads very early on
(not the case here), it is a good idea to call JenaSystem.init().
My regards to Sam,
Andy

Hi,
I've started upgrading my components from 5.0.0 to 5.1.0 and I run
into the following stacktrace when creating a remotefuseki connection
I suspect an initialization issue, but I cannot find any reference in
the release notes.
