Bug 20213 Code assist could show static methods|fields with different icons
It would be good if one could distinguish between static methods and normal methods within the code assist. Eg. Thread.sleep(xxx) is static, but if you use Thread t=Thread.current(); t.sleep(xxx); you could think is local method.
