troizet opened a new issue, #6290:
URL: https://github.com/apache/netbeans/issues/6290
### Apache NetBeans version
Apache NetBeans 19 release candidate
### What happened
When performing long operations such as `Background scanning of projects`,
`Refreshing indications`, `Checking for external changes`, a progress bar
appears at the bottom. When clicking on the progress bar, a popup window opens,
in which an exception `java.lang.IllegalArgumentException: Wrong parent window`
is thrown when clicking on `Click to cancel process`.
### How to reproduce
- Click on the progress bar when performing operations such as `Background
scanning of projects`, `Refreshing indications`, `Checking for external
changes`.
- Click on `Click to cancel process` in the popup window that opens.

### Did this work correctly in an earlier version?
Apache NetBeans 18
### Operating System
Debian GNU/Linux 12 (bookworm)
### JDK
OpenJDK Runtime Environment 17.0.7+7-Debian-1deb12u1
### Apache NetBeans packaging
Apache NetBeans binary zip
### Anything else
Stacktrace:
