| * <code>thread</code>; all other threads will be unaffected. |
| * A <code>size</code>value of {@link com.sun.jdi.request.StepRequest#STEP_MIN} will generate a |

| * smallest step size available and often maps to the instruction |
| * level. |

| * step event each time the source line changes unless line number information is not available, |
| * in which case a STEP_MIN will be done instead. For example, no line number information is |
| * available during the execution of a method that has been rendered obsolete by |
| * by a {@link com.sun.jdi.VirtualMachine#redefineClasses} operation. |
| * A <code>depth</code> value of {@link com.sun.jdi.request.StepRequest#STEP_INTO} will generate |
| * step events in any called methods. A <code>depth</code> value |
| * of {@link com.sun.jdi.request.StepRequest#STEP_OVER} restricts step events to the current frame |
| * or caller frames. A <code>depth</code> value of {@link com.sun.jdi.request.StepRequest#STEP_OUT} |
| * restricts step events to caller frames only. All depth |
| * restrictions are relative to the call stack immediately before the |
| * step takes place. |
| * <p> |
| * Only one pending step request is allowed per thread. |
| * <p> |
| * Note that a typical debugger will want to cancel stepping |
| * after the first step is detected. Thus a next line method |
| * would do the following: |
| * <code> |
| * <pre> |
| * EventRequestManager mgr = myVM.{@link VirtualMachine#eventRequestManager eventRequestManager}(); |
