  • Tracking object fields using relocatable object watchpoints
    Patent number: 8489652
    Abstract: A method for managing an object watchpoint during a garbage collection cycle, including identifying an object having a field, where the object is associated with an original object location, where the field is associated with an original field location, and where the object and the field are located in a memory heap of a virtual machine memory, setting, within a debugger, the object watchpoint on the original field location, where the object watchpoint is a memory trap associated with the object, determining, after a relocation of the object by a garbage collector (GC), a new object location associated with the object, determining a new field location of the field based on the new object location, and setting, within the debugger, the object watchpoint on the new field location.
