Comment #17 on issue 598 by [email protected]: Persist Extension:
PersistService.start() cannot be called multiple times
https://code.google.com/p/google-guice/issues/detail?id=598
I solved the problem by creating my own class extended
JpaPersistService with the overloaded method:
@Override
public synchronized void start() {
try {
super.start();
} catch (IllegalStateException e) {
; // no worries if it's already running.
}
}
I then added bindings for my class to the injector:
bind(PersistService.class).to(MyJpaPersistService.class);
bind(JpaPersistService.class).to(MyJpaPersistService.class);
bind(MyJpaPersistService.class).in(Singleton.class);
It sounds like Xavier did the equivalent using Guice's AOP features:

Our application encounters the problem in a similar way as #15
describes: We attach to the database with one configuration to do
things like database migrations, and then reconfigure for normal use
with more limited permissions.
