In the reconnecting progress bar we can see an extral line menu divider (may be) above the cancel button.

How to produce this.
1) login to any solaris-sparcv9 machine
2) start jconsole.
3) connect to any java application ( even to jconsole in this local process list).
4) disconnect (with icon).
5) connect back by clicking on icon.
6) you should see an extral line in the reconnecting dialog box.
This doesn;t come in windows build.

screen shot is attached with this.
