Hi.  

That was almost an excellent SSCCE you posted, but if you 
make some trivial changes, it is possible to post just a single 
(.java) file that helps people see it easier.

The way you would do that is (the same way I just
did to see the code run as Test.java)
- Move all the imports to the 'top'
- demote the 'public class Line' to 'class Line'
- ..that's about it, actually.

The thing is - it is easier for you to do that before posting,
than for two other people to do it while before seeing the 
problem.

I am not entirely sure I understand.  But I will take a shot.

If you mean that 'the bottom component' is not getting events
when the mouse passes over the 'top component' then I think
that makes sense.

The top component is 'consuming' the events before they 
reach the bottom component.

>Kindly advice on how to overcome this problem

I am not sure that you are following the correct strategy here.

If I were the user about to drag either of those components, I
would expect the 'top one' to be dragged whenever the pointer 
is within its bounds.  Why would I want the bottom one to 
get the events?  

If need be, I might even drag the top one out of the way 
for the moment, just to get at the bottom one.

I suggest instead that you draw an 'animated outline' of the 
bounds of the 'selected' line - then I think it would be fairly
intuitive for the user.  Also, a way to 'reorder' the layering 
might be handy.

What is this all for, by the way?  I can think of a number of 
interesting types of things you might do with this, but what
is this one used for?
