Hi @mistermax80 , seems to be a swing issue but needs confirmation.

According to the error logs you pasted - maybe swing API issue with current Java version or some image icon not found issue Null pointer issue. Can you check if image it's trying to access is present or not in your local ?

Thanks,
Aditya

hi @mistermax80 ,
make sure that you are not inadvertently setting the classIcon field of the CompletionPanel to null before invoking getIconWidth()
