| * @summary converted from VM Testbase nsk/jdi/ThreadReference/popFrames/popframes003. |
| * VM Testbase keywords: [quick, jpda, jdi] |
| * VM Testbase readme: |
| * DESCRIPTION: |
| * The test for the implementation of an object of the type |
| * ThreadReference. |
| * The test checks up that a result of the method |
| * com.sun.jdi.ThreadReference.popFrames() |
| * complies with its spec: |
| * public void popFrames(StackFrame frame) |
| * throws IncompatibleThreadStateException |
| * Pop stack frames. |
| * All frames up to and including the frame are popped off the stack. |
| * The frame previous to the |
| * parameter frame will become the current frame. |
| * After this operation, this thread will be suspended at the invoke |
| * instruction of the target method that created frame. |
| * The frame's method can be reentered with a step into the instruction. |
| * The operand stack is restored, however, any changes to the arguments that |
| * occurred in the called method, remain. For example, if the method foo: |
| * void foo(int x) { |
| * System.out.println("Foo: " + x); |
| * x = 4; |
| * System.out.println("pop here"); |
| * } |
| * was called with foo(7) and foo is popped at the second println and resumed, |
| * it will print: Foo: 4. |
| * Locks acquired by a popped frame are released when it is popped. |
| * This applies to synchronized methods that are popped, and |
| * to any synchronized blocks within them. |
| * Finally blocks are not executed. |
| * No aspect of state, other than this thread's execution point and locks, |
| * is affected by this call. Specifically, the values of fields are unchanged, |
| * as are external resources such as I/O streams. Additionally, |
| * the target program might be placed in a state that is impossible with |
| * normal program flow; for example, order of lock acquisition might be |
| * perturbed. Thus the target program may proceed differently than the user would expect. |
| * The specified thread must be suspended. |
| * All StackFrame objects for this thread are invalidated. |
| * No events are generated by this method. |
| * None of the frames through and including frame may be native. |
| * Not all target virtual machines support this operation. Use |
| * VirtualMachine.canPopFrames() to determine if the operation is supported. |
| * Parameters: frame - Stack frame to pop. |
| * frame is on this thread's call stack. |
| * Throws: UnsupportedOperationException - |
| * if the target virtual machine does not support this operation - see |
| * VirtualMachine.canPopFrames(). |
| * IncompatibleThreadStateException - |
| * if this thread is not suspended. |
| * IllegalArgumentException - |
| * if frame is not on this thread's call stack. |
| * NativeMethodException - |
| * if one of the frames that would be popped is that of |
| * a native method or if frame is native. |
| * InvalidStackFrameException - |
| * if frame has become invalid. Once this thread is resumed, |
| * the stack frame is no longer valid. |
| * The test checks up that locks acquired by a popped frame, |
| * are released when it is popped. |
| * This applies to synchronized methods being popped. |
| * The test works as follows: |
| * The debugger program - nsk.jdi.ThreadReference.popFrames.popframes003; |
| * the debuggee program - nsk.jdi.ThreadReference.popFrames.popframes003a. |
| * Using nsk.jdi.share classes, |
| * the debugger gets the debuggee running on another JavaVM, |
| * creates the object debuggee.VM, and waits for VMStartEvent. |
| * Upon getting the debuggee VM started, |
| * the debugger calls corresponding debuggee.VM methods to get |
| * needed data and to perform checks. |
| * In case of error the test produces the return value 97 and |
| * a corresponding error message(s). |
| * Otherwise, the test is passed and produces |
| * the return value 95 and no message. |
