IOException blocks SOAPUI from exiting

[spotlesscoder]

I opened an existing file in SOAPUI and made some changes. But did not save the file yet.

Then the file changed outside SOAPUI because I checked out a different branch in the SCM where the SOAP project file was taken from.

Then I completely deleted the checked out working copy. Then I wanted to close SOAPUI.

Clicking the X on the window manager opens a dialog "Exit? Yes/No". When clicking "Yes", I get an error message with an IOException.

I think this has something to do with the "File has changed outside of SOAPUI - overwrite?" dialog that normally pops up when the file was changed outside SOAPUI and you want to exit SOAPUI
