How the breakpoint debug work in the IDEA?

We had developed a java agent called HotCode like JRebel and I try to write a plugin to run Servers with the this java agent . and it works . (http://plugins.jetbrains.com/plugin/7564?pr=idea)
but I found that the breakpoint don't work because that we change the class file with asm in HotCode, so the debugger vertify fail and breakpoint will not work.
Any suggestion?  I found some infomation about it, like

DebuggerManagerEx.getInstance(project).addBreakPointManagerListener#breakpointsChanged() events to listen to added/removed events. ? does it work?

and should i create a line map for the source and the changed classes?

and how can i do for don't debug into the HotCode Agent Proxy Code?
