[jdt-debug-dev] javamethodbreakpoint trace

["Jago Westmacott" <jago.westmacott@xxxxxxxxxxxxxx>]

Hi,  
I'd be grateful for any help with the following:
Say I put a JavaMethodBreakpoint on java.util.Vector's .setSize() method, create several instances of a Vector 
and call the .setSize() method on each instance in some sample code that is run.  My BreakPointListener gets notified every method call, but how can I discover which Vector's instance's method was called?  Simplistic example:
Vector v1 = new Vector();
Vector v2 = new Vector();
v1.setSize(1);
v2.setSize(2);
With the above lines of code, how can i tell from my breakpointHit method if the event is occurring on v1 or v2 instance of Vector?
I had some luck with looking up line numbers via the stack frames, but haven't managed to get reliable or consistent results (and it feels wrong).
Many thanks
