7.1 Dev Build 201110040601 - Project that exhibits the error.

Try to drag the top of jButton3 up and snap it to the top of jButton2. 

It throws this error.

Probably has to do with the Filler (glue) on the panel.

I am sorry, I am not able to reproduce this exception (AssertionError from LayoutFeeder.mergeSequentialInclusions). The attached test-case throws a different exception when I use either Build 20111004 or the latest development build. I have submitted a separate issue for that exception (see issue 203656).

I am closing this issue as incomplete because there is no reproducible test-case for the original exception. Feel free to reopen this issue if you find such a test-case. Thank you in advance.

I've found a reproducible test case. Just resize jButton3 to align at top with the other components.
