[Soot-list] Creating Traps

[Alessio Gambi]

Dear SOOT-ers,

this is a newbie question but I cannot find any relevant answer around. 

The problem:
	Instrument an Android application such that all the methods of the application are wrapped in a “big” try/catch-all-exceptions.
	The catch block traps Throwable and simply rethrows whatever was trapped

I need this to be able to observe/monitor at runtime what exceptions are thrown by the various methods, as part of a larger project.

I understand that I need to add create a new Trap and add it to the method body by providing four inputs: the exception, the start unit, the end unit, and the first unit of the handler.

So far I managed to provide three of the four inputs, namely, exception, start unit and handler units, but I cannot wrap my mind how I can find out the end unit as that would be excluded
from the trap scope. I suspect might simply be the last unit of the method (i.e., return/throw).

Also, adding the trap to the body is a two-step process: adding the body of the trap (handlerStmt and followingStmts) and “declaring” the trap via addTrap(). Would that be correct?

Thanks
