lannybroo opened a new issue, #7126:
URL: https://github.com/apache/netbeans/issues/7126
### Apache NetBeans version
Apache NetBeans 21
### What happened
What happens is that I copy some text from some of my Java source code in
the NetBeans editor using `⌘ C` (I'm on macOS Sonoma 14.3.1) then click
somewhere else in the NetBeans editor and try to paste that code via `⌘ V`.
This first paste attempt fails every time. Nothing is pasted and the state of
the editor window stays the same. If I watch carefully I see that the `Edit`
menu does flash during this first paste as it does when running any keyboard
command that is also in the menu in NetBeans. If I then try pasting a second
time via `⌘ V`, the paste succeeds. I can then paste over an over again and
each subsequent paste succeeds until I copy something new.
What I expect to happen is for paste to always work.
The problem also occurs in the same way if you use the `Edit > Copy` then
`Edit > Paste` menu commands instead of keyboard shortcuts.
The problem *does not occur* if you copy text from a different application
(not NetBeans) and then paste into Netbeans. In this situation, the first paste
into NetBeans succeeds.
I do not think this is related to existing open copy/paste issues such as
#3962 or #5948.
### Language / Project Type / NetBeans Component
_No response_
### How to reproduce
1. Copy some text in a NetBeans editor window
2. Paste the text .. this first time won't work
3. Paste the text again ... this time and later will work
### Did this work correctly in an earlier version?
No / Don't know
### Operating System
macOS Sonoma 14.3.1 on aarch64 (ARM M1 Mac)
### JDK
11.0.17; OpenJDK 64-Bit Server VM 11.0.17+8-LTS (Zulu)
### Apache NetBeans packaging
Apache NetBeans provided installer
### Anything else
This happens every time when copying from within NetBeans, as described
above.
I'd be happy to help test/debug any fix ideas but I am too unfamiliar with
this code base to work up a PR at this time.
I also grabbed a snip of an exception I see in `View > IDE Log` after the
2nd paste (that succeeds). Interesting I didn't see this exception after the
1st (failing) paste:
