paragraphs ids duplicated when using HTMLDocument with JTextPane

    Details

      Description

      FULL PRODUCT VERSION :
      java version "1.7.0_21"
      Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
      Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)

      A DESCRIPTION OF THE PROBLEM :
      If you use a HTMLDocument inside a JTextPane,
      the id of current paragraph is propagated to the newly created paragraph when pressing return key :
      <p id="test">test</p><p id="test"></p>

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Create a JTextPane, set an HTMLDocument as document, load this html inside :
       '<html><head></head><body><p id="test">test</p></body></html>'

      Then, press return key after "test" to create a new paragraph. The document now contains :

       '<html><head></head><body><p id="test">test</p><p id="test"></p></body></html>'

      The id has been duplicated which is, of course, unexpected

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
       '<html><head></head><body><p id="test">test</p><p></p></body></html>'
      ACTUAL -
      <html><head></head><body><p id="test">test</p><p id="test"></p></body></html>

      REPRODUCIBILITY :
      This bug can be reproduced always.
