🚀 go-pugleaf

I have an application written in jbuilder2. when i execute it
and  press a button (action performe) i always see one of the  next 3
messages.
when i'm doing debbuging noone  of these messages appears and the program
works good.
does anybody have an idea what can it be?

The messages are:
1.
Exception occurred during event dispatching:
java.lang.NullPointerException
