Oracle on Java EE 8 News, Monitoring, Sonar Setup, BCE Entities or 29th Questions and Answers

90 live attendees from all over the world (according to chat: France, Nigeria, Costa Rica, Netherlands (...)) participated in the 29th edition of starting with the "Oracle and Java EE 8" discussion including press releases, then I answered questions ranging from Akka interoperability, over Java EE monitoring, to file access from EJBs and Sonar Setup:

We use SonarQube with a huge ear application, Arquillian and Embedded Payara.
Code coverage is reported via Jacoco; CDI/EJB injection in tests have some problematic scenarios, but generally it works.

@Alternative is perfectly suitable to mock something for tests.

I will write some blog about that soon ... the important message from me is that it really works :-)

Hi Adam,
on the question of how to handle WebSocket timeouts, setting maxIdleTimeout will not work as you suggested because a connection will only be idle if it is not receiving or sending messages. In this case the application is pumping messages to connection(s). I would suggest the questioner implement an onClose listener without CloseReason (to catch all reasons) that checks the Throwable passed to it to see what is happening to the underlying connection.
