FileEditorProvider java.lang.Throwable

Hi community,

i registered my fileEditorProvider as an Extension in plugin.xml. It's working fine, tab with new editor shows under the default editor. I can work with this new editor like everything is fine, but every time when i open file asociated with my new editor the following error shows up (but still I can work with new editor and switch between editors like everything is fine, and this error shows only when I open file from project structure) :
