Thread-Safety

[Harald Wellmann]

Is an EntityManager injected from the Aries JPA container thread-safe, 
just like in Java EE?

Going one level higher, is an OSGi service injected via Blueprint into a 
web component thread-safe, like an EJB?

I wouldn't think so, but does Aries offer some support for wrapping 
services in a thread-local or pooling proxy, or some other best practice 
for making services thread-safe?

Best regards,
Harald
