Description
Let's see 4 cases:

1) first font is equal to the second one:
        Font f1 = new Font( "serif", Font.BOLD, 12 );
        Font f2 = new Font( "serif", Font.BOLD, 12 );
        System.out.println( f1.equals( f2 ) );
EXPECT: true
ACTUAL: true

2) first font is equal to the second one:
        Font f1 = new Font( "serif", Font.BOLD, 12 ); f1.getAttributes();
        Font f2 = new Font( "serif", Font.BOLD, 12 );
        System.out.println( f1.equals( f2 ) );
EXPECT: true
ACTUAL: false

EVALUATION This is a duplicate of 6487386: Font.equals() incorrectly returns false if getAttributes() is called on just one of the fonts This is already fixed in JDK7 (b03?) and is also fixed in JDK 6u1 b01

EVALUATION When we call font.getAttributes(), font.values private field is created. At the same time Font.equals() method takes this field into consideration, so if font1.values is null and font2.values is not null, then font1.equals(font2) is false.
