In the JMS Property Window, if you run the UI Accessibility Tester, there are items that do not have a LABEL_FOR and 
is not accessibile through tab traversal

Steps to reproduce:
1.  Create a .wsdl using the JMS Binding.
2.  In the WSDL Editor, select the jms:address node under Services > jmsService > jmsPort
3.  It will open a Property Window
4.  Run the A11Y Tester on this property window.

You will get the following A11Y errors:
0 Components with no LABEL_FOR pointing to it :
   Class: org.openide.explorer.propertysheet.SheetTable {  Properties table |  Table of editable properties 
representing the current object } 

- Components not reachable with tab traversal :
   Class: org.openide.explorer.propertysheet.SheetTable {  Properties table |  Table of editable properties 
representing the current object }
