When user try to reconnect target edge and put the cursor on empty area (around 5sec) on diagram with click left always pressed, an exception  "Unhandled event loop exception" appears in errorLog (nothing in console).

You will get the following stack
>org.eclipse.swt.SWTException: Failed to execute >runnable(java.lang.ArithmeticException)
>	....
>Caused by: java.lang.ArithmeticException

Error amso noticed during homologation of 4.1.3


Steps to reproduce: 
> Import the attached project 
> Open the session and the (single) diagram in it. It should show two packages p1 and p2, two classes C1 and C2 and an edge from C1 to C2.
> Try to reconnect the edge from target end on package P1 and then always with click left pressed, put the cursor on empty area between P1 and P2. 

Another Scenario :
> Import the attached project 
> Open the session and the (single) diagram in it. It should show two packages p1 and p2, two classes C1 and C2 and an edge from C1 to C2.
> Try to reconnect the edge from target end on class C1 always with click pressed during 5sec on C1
