I have the same application in tomcat 7 and tomcat 8 , only in tomcat 8 of a problem, src of an image but in the files of the images that has accentuation of a not found error, it follows images:
filename: FAVORITOS-MENU - SEM SELEÇÃO_e86aff0a5ad040e3b0232a075079dd46.png
If I change SELE%C7%C3O
by SELEÇÃO
direct in the link it works normally ...
and remembering Tomcat 7 works normally!
