I have code that all over the place(probably 20-30 instances) does this:

<widget>.setVisible((condition == VIEW) || (condition == EDIT));

    Disassemble the class file with javap, e.g.

    javap -c com.example.ClassName
    

    to see the bytecode source. But why not just guarantee the optimization by extracting into a temp boolean variable?
