      Description

      (Regards build #226 20210103-release)

      When scanning certain projects for the first time Netbeans reports a java.lang.AssertionError, it looks like it's caused by the css parser. The error does not reappear when opening the project for the second time, but when I delete the Netbeans cache folder the scanning happens again and the error reappears.

      I attach a simple project to reproduce it - it essentially contains only tinymce editor library, I suspect one of its minimized css files might be causing the problem.

      Here is the error:
