VanillaCompilerWorker throws NPE in (aono) ThreePathScanner visitNewClass

### Apache NetBeans version

Apache NetBeans 26

### What happened

While opening a NetBeans module with NetBeans, you get an error bulb in the status line.
The stacktrace included in the report mentions that nc.clazz.type is null in that case.

### Language / Project Type / NetBeans Component

java source base

### How to reproduce

Open a NetBeans module.

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

No / Don't know

### Operating System

ubuntu 24.04

### JDK

jdk 17 & 21

### Apache NetBeans packaging

Apache NetBeans binary zip

### Anything else

Should add stack trace, but lost that after analyzing.

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

Yes

Start by opening a NetBeans module on Ubuntu 24.04 with JDK 17 or 21 and reproduce the error bulb. Inspect VanillaCompilerWorker and ThreePathScanner.visitNewClass, focusing on the reported null nc.clazz.type; done means opening the module no longer produces the NPE or error bulb.
