Trying to verify the bug http://monaco.sfbay.sun.com/detail.jsf?cr=6458123 

Since there is a compilation issue with the test case from the 6u23 ws at http://jdksrc.sfbay.sun.com/hg/6u23/Jcg/j2se tracked under http://monaco.sfbay.sun.com/detail.jsf?cr=6997384, 

Used the test case from the 7ws (test http://closedjdk.sfbay.sun.com/jdk7/swing/jdk/test/closed/javax/swing/JMenuItem/6458123/bug6458123.java) to verify the bug 6458123.   
I'm getting the following exception and the test is failing with 

checkLabelRect() passed
checkBounds() passed

whereas this test passes with jdk7-b116-PIT build, so this could be a regression.  Please see the attached log file
