A DESCRIPTION OF THE PROBLEM :
Only with the Mac OS X Aqua look and feel (apple.laf.AquaLookAndFeel), when JTabbedPane setTitleAt(index,title) replaces an HTML-formatted title, all previously existing titles are incorrectly pushed over.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached program on a Mac with the Aqua look and feel:
java -Dswing.defaultlaf=apple.laf.AquaLookAndFeel bug6670274
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The attached program (copied from: http://bugs.java.com/view_bug.do?bug_id=6670274) creates three tabs initially:
0 = "one"
1 = "<html><i>Two</i></html>"
2 = "three"
It then does:
pane.setTitleAt(0, "ONE");
The expected result is:
0 = "ONE"
1 = "<html><i>Two</i></html>" (HTML-formatted)
2 = "three"
ACTUAL -
Run the attached program on a Mac:
java -Dswing.defaultlaf=apple.laf.AquaLookAndFeel bug6670274
Instead of the expected result, you see this:
0 = "ONE"
1 = "<html><i>Two</i></html>" (as raw text, not HTML-formatted)
2 = "<html><i>Two</i></html>" (HTML-formatted)
The title "three" has been pushed off the end.
Other look and feels generate correct results:
java -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel bug6670274
java -Dswing.defaultlaf=javax.swing.plaf.nimbus.NimbusLookAndFeel bug6670274
This bug has apparently already been fixed in Java 9; apple.laf.AquaLookAndFeel generates correct results in a Java 9 EA release.
REPRODUCIBILITY :
This bug can be reproduced always.
