Den Solo reports:

Object[] data = new Object[2];
data[0] = 1;
data[1] = 2;
boolean is1 = data[0] == 1;
boolean is2 = data[1] == 2;
System.out.printf("%b, %b", is1, is2);

Please have a look at this code - it can't be compiled because of "incompatible types: java.lang.Object and int" for lines
4 and 5. But Idea doesn't highlight these lines as erroneous..
