wrong line for method execution join point

added in docs dir.

 	Special case if(false) to not require a dynamic test

effect of an after returning type incompatible with a join point return type

   duplicate warning or second join point for constructor-execution

   Erroneous exception conversion 
and Bugzilla Bug 34206  
   before():execution(new(..)) does not throw NoAspectBoundException 

All exceptions that occur during the static intialization of a persingleton

   XLint warning for call PCD's using subtype of defining type 

also added extraSourceLocations to IMessage+ for

 * fix to semantics document to describe correct semantics
 * checkin of failing coverage test case for correct semantics

	  	binary aspect-declared methods conflict, lost their exception clauses

larger fix to address more issues with aspect-declared methods in bytecode form
also addressed declared exception issue more generally

this fix should be more stable than a smaller hack that just fixed this specific bug
