Project that exhibits the error.

1) Open NewJPanel.java.
2) Right-click jTextField1 in designer and choose "Duplicate".

This error occurs.

This occurs on many other components if they are added to the Panel.

I was able to reproduce the metioned exception using the attached test-case.

It seems to be a duplicate of issue 203272. Automatic exception reporter filled a new issue because the stack-trace is not exactly the same, but the difference is minor: there is just one more call to shouldDuplicateWholeGroup() in issue 203272. In other words, the same problem occured to a group that is nested deeper.
