AWT events not allowed exception while trying the plugin for the first time on IntelliJ

[Former user]

Hi,

I am running IntelliJ versiom 2019-1 on Ubuntu bionic64 in a VirtualBox VM.

vm: * cpus: 4 * memory: 12GB * disksize: 90GB

I tried the pluging for the first time and didn't get any diagram but an exception. I did the exercise multi-time to make sure, and with some restart of IntelliJ. But still te same error occurs.

Here is the stack trace I am getting:

• java.lang.Throwable: AWT events are not allowed inside write action:
