Subject [jira] Created: (HARMONY-1456) [classlib][awt]java.awt.Font.hasUniformLineMetrics() return true on Harmony while RI returns false
Date Wed, 13 Sep 2006 14:35:23 GMT
[classlib][awt]java.awt.Font.hasUniformLineMetrics() return true on Harmony while RI returns
false
--------------------------------------------------------------------------------------------------

                 Key: HARMONY-1456
                 URL: http://issues.apache.org/jira/browse/HARMONY-1456
             Project: Harmony
          Issue Type: Bug
          Components: Non-bug differences from RI
         Environment: Windows XP
            Reporter: Ilya Okomin
            Priority: Trivial


According to the specification method must Font.hasUniformLineMetrics return true if this
Font has uniform
line metrics; false otherwise.
RI returns false for physical font "Arial" while Harmony returns true.
====================test.java====================
import java.awt.*;

import junit.framework.TestCase;

public class test extends TestCase {

    public void testRun() {
        final String name = "Arial";
        
        Font f=new Font(name, Font.BOLD, 12);
        
        // Check if created font is physical, it's family name 
        // is not logical and equals to the name parameter.
        assertEquals(f.getFamily(), name);
        assertTrue(f.hasUniformLineMetrics());                       
    }
}

Harmony: java version "1.5.0" 
pre-alpha : not complete or compatible
svn = r431938, (Aug 16 2006), Windows/ia32/msvc 1310, release build
http://incubator.apache.org/harmony

// test passed!

I would suppose that it is RI bug, since spec says: " If the logical Font is a single font
then the metrics would be uniform." In this case we have "Arial" font that is a single physical
font on Windows platform and according to spec it has to have uniform metrics.
