One breaks, the other doesn't

I'm using Jswat 3 build 200505031930.

Two classes with a main, in the same ant build compile task, classes and 
srcs located in the same directories. From the setting sin Jswat, the 
sessions for each seem to be the same....

Class-A breaks at set breakpoints. Class-B goes right past the set 
breakpoints.  The class is going there as there is output being written 
in and a round the breakpoint..  But no stopping...

What setting/flag did I miss?

TIA,

Roy
