gwt plugin breaks java code minings

oh how long i searched why my eclipse is refusing to show me references code minings, but when i tried to set up new eclipse they worked.... until i installed gwt plugin again. As soon as i removed gwt plugin references started working again. All of this is so even if i force eclipse to use "Java editor" instead of forced upon "GWT Java editor"(which is frustrating in a combined project enviroment on it's own, as is a forceful inclusion of gwt sdk in build path when it's already included with maven, and it's causing problems on it's own)

example with gwt installed in "Java Editor":

example without gwt installed in "Java Editor":

Beginne mit installiertem GWT Eclipse plugin und vergleiche das Code-Mining-Verhalten des Java editor mit den Screenshots und mit derselben Eclipse-Konfiguration ohne das plugin. Es werden keine Quelldateien oder Tests genannt; abgeschlossen ist die Aufgabe, wenn Java references code minings im Java editor funktionieren, während das GWT plugin weiterhin installiert ist.
