Impossible to debug unit test based on TestNG when the package is named a certain way

### Apache NetBeans version

Apache NetBeans 22

### What happened

When a TestNG unit test is named
com.basic.xml, com.basic.xmltoto but not com.basic.totoxml the test cannot be run in debug mode.
It doesn't find the class.
It's because the package suffix starts with xml.

### Language / Project Type / NetBeans Component

Java application project with Ant

### How to reproduce

Create a package com.basic.xmltoto
Create a class in it, add a test method (annotated with @Test) and run this method in debug mode

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

No / Don't know

### Operating System

Windows 11

### JDK

Java 21

### Apache NetBeans packaging

Apache NetBeans provided installer

### Anything else

The problem occurs systematically

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

Reproduce the issue in a Java application project with Ant using Apache NetBeans 22: create package com.basic.xmltoto, add a class with a TestNG @Test method, and run it in debug mode. Trace the TestNG debug launch from the project or test-run entry point and verify that debugging finds the class for packages whose suffix starts with xml.
