When do you create/add the breakpoints? If you create them after the
launch, the target execution may complete before you add the breakpoints.
I notice that you have commented out the line to "stop in main" which look
suspicious.
Note that JavaLineBreakpoint is a private internal implementation class
that is not intended to be subclassed by other plugins.
If you could provdide us with a reproduceable (small) example, it would be
easier to diagnose the problem.
