EVALUATION The bug is in javax.swing.text.html.CSS.getFontSize() method. It can be emulated with the following code [or reproduced on system that returns 64 to the following call: <code>Toolkit.getDefaultToolkit().getScreenResolution()</code>, e.g. on the mentioned Solaris 8 x86 with OpenWindows instance]: [code] System.out.println("****************"); int res = 64; System.out.println("res = " + res); float scale = res / 2.54f; System.out.println("scale = " + scale); float value = 2.54f * scale; System.out.println("value = " + value); int value_int = (int) value; System.out.println("value_int = " + value_int); int value_int_rounded = Math.round(value); System.out.println("value_int_rounded = " + value_int_rounded); System.out.println("****************"); [code] The output is: **************** res = 64 scale = 25.19685 value = 63.999996 value_int = 63 value_int_rounded = 64 **************** Float value of 63.999996 is incorrectly _casted_ to int resulting in 63 and not 64. In the test it leads to the wrong font size of 63 for the 'E' symbol. ###@###.### 2005-05-26 16:35:40 GMT
