Steps to reproduce:
1) Create a class with method

aMethod() {
.  System.out.println("a"); // set the breakpoint to the line
}

2) Start debug session which uses the method aMethod. The debugger correctly
stops at  the line 
.  System.out.println("a"); // set the breakpoint to the line

3) change the method to the:

aMethod() {
   System.out.println("b");
.  System.out.println("a"); // set the breakpoint to the line
}

4) apply code changes
The debbuger now stops at line 
System.out.println("b");

The debugger stops on the line 
.  System.out.println("a"); // set the breakpoint to the line
after restarting debugging session
