Bug#925510: netbeans: Netbeans not usable with java in Buster

[Wouter Wijsman]

Package: netbeans
Version: 10.0-3
Severity: important

Dear Maintainer,

I've installed the netbeans package on my Buster installation for Java
development and it is behaving is some very weird ways for me. I
installed it with apt-get.

I also installed Netbeans with Flatpak to see if that worked any
better.
I have not seen any of the issues I'm seeing with the version in the
repo
with that version. The issues I am seeing with the repo version also
very consistent. I can reboot and restart netbeans however many times I
want, they always happen. Updating the system didn't change anything
either.

The following issues have been happening:

Creating a project doesn't work like expected. When you click on finish
in the dialog, the loading screen finishes incredably fast, but then
nothing happens. When looking at the directory where the project should
have been created, you can see it is there. Loading the project doesn't
work well, though. Netbeans does not detect the files or even the
package found in a project created like this.

When I open a project which has been created by a working version of
netbeans, the project is loaded much slower than expected. Instead of
the usual couple of seconds, it takes more than 10 seconds. The
navigator never fills up and just shows please wait. Trying to run the
project doesn't do anything either.

Creating a new java class is weird too. When clicking Finish, the
loading bar goes very fast and the file is created, but I get an error
stating "The file newclass.java already exists". The dialog doesn't
close by itself.

I think it is very likely to all be caused by an error which show up at
the bottom of the screen. The red balloon in the bottom bar reveals an
"Unexpected Exception". The summary of the error is as follows:

A java.lang.NoSuchMethodError exception has occurred.
Please report this at

including a copy of your messages.log file as an attachment.
The messages.log file is located in your
/home/wouter/.netbeans/10.0/var/log folder.

I hope that helps. I can provide more information if needed.

Kind regards,
Wouter
