In many cases, in order to get interesting or in-depth results the

ExtendedDTraceProbes flag needs to be set when DTracing Java programs. In

this case, because of the probes we have chosen to trace, running the program

Code/Java/Func_abc, both with (PID 311517) and without (311526) this flag,

and we can see that it has made no difference, with each reporting 35 lines

executed.
