Hi,
Hugi and I converted a large concurrent application from EOF to Cayenne over
the last few months, and we tried taking it into production today for the first
time. Mostly went fine, but we hit one problem:
Exception in thread "Thread-57" org.apache.cayenne.CayenneRuntimeException:

There is only one application instance with one Cayenne stack. I do have other
cases where the exact same code path did not produce problems, both before and
after this exception happened. There's a lot of concurrency in this
application, so it might only happen when this leads to a new connection being
opened?
Any help is greatly appreciated.
Thanks
Maik
