Jakarta EE 9.1 - EJBs not found by "Call Enterprise Bean" (insertion into another class)

### Apache NetBeans version

Apache NetBeans 16 release candidate

### What happened

If you want to insert an EJB in another EJB (for example) with the help of NetBeans, no EJB is found.

### How to reproduce

Alt-Insert in the code of a class and choose "Call Enterprise Bean".

### Did this work correctly in an earlier version?

Apache NetBeans 15

### Operating System

Windows 11 Family 64-bit, version 21H2

### JDK

11

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

It worked in the previous versions but with Jakarta EE 8.

### Are you willing to submit a pull request?

No

### Code of Conduct

Yes

Start at the Alt-Insert "Call Enterprise Bean" action and trace how EJBs are discovered for Jakarta EE 9.1 projects. Compare the behavior with Apache NetBeans 15 and verify on the reported Windows 11 and JDK 11 setup that available EJBs appear for insertion into another class.
