The same error exception is thrown following these steps, - Create a new JSP using the IDE's "New" menu steps, as usual - Right-click on the newly created file... The normal context menu pops up without errors. - Rename or copy/paste the JSP to have a different name. - Right-click on the newly renamed/pasted file... A FileStateInvalidException is thrown.
