Eclipse not showing code in the Java Editor perspective

Issue

I was working in Eclipse with some packages and then suddenly the java editor perspective doesn't show any code and it's blue, just like in the photo bellow:

I tried everything, from resetting the perspective to cleaning the project, even installed a new version of Eclipse. If i select the entire content of the .java file then pass it to a txt file the code is still there.

Solution

It seems like after 2 days Eclipse just started working normal.
