in spring configuration file create new <bean> element. In 'class' attribute value type the class short name. Put the cursor somewhere in the middle of the name and press Ctrl-Alt-Space. In the appeared list select the correct class by Enter or mouse.
----> the class full name is substituted, but with 1 symbol cut.
It seems that the n+1 symbol is removed where n is the class short name length.
If the cursor is placed in the end of the name to complete (after last symbol), no problems occur
