NPE triggered by Compilation job

### Apache NetBeans version

Apache NetBeans 26

### What happened

Playing with a reporters example I happened to trigger an NPE.
I will add the source code as zip file and see if I can reproduce the sequence of events.

For now, here is the stack trace:

```shell

### Language / Project Type / NetBeans Component

java, module java.base

### How to reproduce

I am working on that.
But from my head: implement a private field with getters and setter in the top most class in the example zit file.
I am sure the I did not explicitly invoke the compiler. Compile on save is off.
It is probably trigger by some analysis process.

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

No / Don't know

### Operating System

ubuntu 24.04

### JDK

21

### Apache NetBeans packaging

Apache NetBeans binary zip

### Anything else

I am not sure if I can create a fail-safe scenario.

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

Yes

Start with the attached orderexport.zip and the stack trace, then inspect org.netbeans.lib.nbjavac.services.NBAttr.attribClass and the parsing path through JavacParser.java and TaskProcessor$CompilationJob.run. Reproduce the reported analysis-time NPE with Java 21 and NetBeans 26, and consider the issue done when the scenario no longer fails or a confirmed cause is documented with a regression check.
