Questions[netbeans](ubuntu)

After fresh Ubuntu 18.04 installation and afterwards a netbeans installation, netbeans does not start. netbeans was installed with

sudo apt install netbeans

some other java programms (at least Eclipse) do not start too.

when starting netbeans from commandline the JVM prints folowing WARNINGS:

➜  ~ netbeans
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.netbeans.ProxyURLStreamHandlerFactory (file:/usr/share/netbeans/platform18/lib/boot.jar) to field java.net.URL.handler

I have a server for development (Ubuntu 12.04). On that machine, I have a shared folder named "projects". I tried

sudo mount -t smbfs smb://192.168.2.28/projects/myProject /mnt/myProject

on my Ubuntu 11.10 and got the error:

Mounting cifs URL not implemented yet. Attempt to mount smb://192.168.2.28/projects/myProject.

How can I do to solve it? I need to mount the folder to use it with NetBeans.

After updating ubuntu to 12.04 all fonts got bold. I haven't installed themes or configured fonts.

from netbeans about:

Product Version: NetBeans IDE 7.1 (Build 201112071828)

Java: 1.7.0_03; Java HotSpot(TM) 64-Bit Server VM 22.1-b02

I have downloaded an external theme for netbeans. How to apply it? I am using Ubuntu 10.04(LTS)

When I copy something from another window then my terminal and want to paste it into my terminal (on the command line) the paste option in Edit is grayed out. Ctrl+V does not work in GNOME Terminal 2.29.6.

I try to copy form netbeans into a terminal. If I paste it somewhere else, in gedit for example, it gets pasted. So it is copied.

Using Ctrl+Shift+C/V does not work.

Is this a settings of from some sort?
