Hi,
I'm working on an integration test for a Java SE application.
Here's what I'm basically doing:
*# Phase 1:*
Injector i1 = Guice.createInjector(..., new JpaPersistModule("myUnit")); //
all done in my module, but nothing fancy here
// bootstrap some instances
PersistService persistService = i1.getInstance(PersistService.class);
UserService service = i1.getInstance(UserService.class);
// start persist
persistService.start();
// populate database
service.createUser(foo, bar);
...
// stop persist
persistService.stop;
i1 = null;
*# Phase 2:*
Injector i2 = Guice.createInjector(..., new JpaPersistModule("myUnit")); //
all done in my module, but nothing fancy here
// bootstrap some instances
PersistService persistService = i2.getInstance(PersistService.class);
MyApplication app = i2.getInstance(MyApplication.class);
// start persist
persistService.start();
// do some work
app.doSomethingUseful(); <-- doesn't work
This time I get the following Exception:
java.lang.IllegalStateException: Attempting to execute an operation on a
closed EntityManagerFactory.

After debugging it turned out that the highlighted JpaLocalTxnInterceptor
got the JpaPersistService from phase 1 injected, which is (of course)
already closed.
Any idea what happended here? I "fixed" it by removing the
persistService.stop() call in phase 1, but I'm not sure if this behaviour
is to be expected...
Thanks,
Marian
