Changing the language of Oracle error messages in SQL Developer

Hi I want to change the language settings to (English) of SQL Developer.

I've tried many things like

AddVMOption -Duser.language=en 

And sqldeveloper.conf file

And even I've changed my system language and display settings to English and countries to United States. But this error message is not shown as in English. Just this highligted part of this error message is not English. How can change to all display messages to English language?

Thank you. Related image

The interesting thing is even though a lot of message is in English, just the "ORA-01017" message is Turkish. Not all Turkish of this message. Just higlighted part is Turkish :(
