It's not possible to copy from NB a text and paste it in other application. Usually it paste some old text that was copied some times before.
Easy test case.
- Open NetBeans
- select a text and press CTRL + C
- switch to another application, text editor, mail, other instance of NetBeans
- press CTRL + V
- as a result a different text is pasted then was selected.
