In the Project Properties>Libraries dialog box (Ant Java project), after adding a certain number of libraires (somewhere around 5-7), the “+” signs for adding things to Modulepath and Classpath disappear. It seems that they will come back if enough libraries are deleted. When the “+” signs have disappeared, one can still add libraries by right-clicking “Libraries” in the Projects tree. These buttons should not disappear no matter how full the window gets. I am upgrading from NB 8.2 to NB 15, so I don't know precisely know when this bug was introduced, as NB 8.2 had a different dialog box layout.
How to reproduce
Project Properties>Libraries dialog box for an Ant Java project
Click "+" sign to add a library.
Continue to add libraries, and the "+" sign will disappear
Did this work correctly in an earlier version?
Apache NetBeans 12.3 or earlier
Operating System
Windows 10 Professional
JDK
Java(TM) SE Runtime Environment (build 17+35-LTS-2724)
Apache NetBeans version
Apache NetBeans 15 release candidate
