When I opened a java class, I got the following warning in the following line:

MyRec rec = new MyRec();
rec.getField(); <---- should use Class name when accessing static method
 (or something to that effect).

It also puts a yellow marker next to that line.

After I did some other stuff (like compiling, creating a new class etc.),
that warning went away! Now I do not see anything. Any ideas? How can I get
all the warnings back?

Thanks,
Siva
