Hi All,
Please review the following fix for jdk16.
 
Bug : https://bugs.openjdk.java.net/browse/JDK-8041705
Webrev : http://cr.openjdk.java.net/~trebari/swing/8041705/webrev00/
 
Issue : The issue is that, border in DefaultTreeCellRenderer is not removed 
if the margin is null.If we set the Nimbus LAF and then switch to  metal LAF 
nimbus border persists.
 
Fix : Added else part of the if(margins != null) , which will set border with margin
(0, 0, 0, 0) when the DefaultLookup.getInsets(this, ui, "Tree.rendererMargins”) returns  null,
removing the previous margin.
 
Test : Added an automated test.
Tested on all the three platforms. Mach5 link is in JBS.
 
 
Regards
Tejpal
