Illegal synchronous loopback call during Singleton initialization would have resulted in deadlock. (EJB name = aa....aa)

aa....aa: EJB name

Description

Initialization of the Singleton Session Bean failed because during the initialization, there was an invalid loopback invocation that might cause a deadlock.

During the initialization of a Singleton Session Bean, initialization was re-executed for the same Singleton Session Bean.

Action

Check whether the initialization processing is being executed for the same Singleton Session Bean from the @PostConstruct annotation method.

If a different Singleton Session Bean is being invoked from the @PostConstruct annotation method, the dependency based on the @DependsOn annotation becomes invalid and this message is displayed. The invalid example is as follows:

Example

@DependsOn("SingletonA")
@Singleton
@Startup
public class SingletonB implements BIntf {
}
 
@Singleton
public class SingletonA implements AIntf {
 @EJB
 BIntf b;
 @PostConstruct
 void init() {
  b.doB();
 }
}
