Hi Andy,

Will test tomorrow, so my initial idea was correct.

yes, you were correct. I can recrete a similar situation here.

Did anything change inbetween 5.0.0 and 5.1.0 ?

Not obviously. The only nearby things look safe. But initlization 
problems can be due to code far away.

If it all works with added JenaSystem.init() then a fix in Jena can be 
done.

All first point of contact classes that do actual work should have a 
JenaSystem.init() and RDFLinkHTTPBuilder doesn't and never has. "It just 
worked" by natural class initialization.

It isn't even always that some change X is wrong, it can be the overall 
combination of X/Y/Z/... being the cause.

Goodnight from a quiet fire station ;)

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,

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.
