| <h2>Purpose</h2> |
| |
| <p> |
| Return from a void method. |

| <h2>Constraints</h2> |
| |
| <ul> |
| <li> |
| The return type of the current method must be void. |
| </li> |
| </ul> |
| |
| <h2>Behavior</h2> |
| |
| <ul> |
| <li> |
| If the method is synchronized, the object's monitor is released in a way |
| similar to the monitor-exit instruction. |
| </li> |
| <li> |
| The stack frame of the current method invocation is removed from the stack. |
| This includes all its registers becoming invalid. |
| </li> |
| <li> |
| If the stack is now empty, the current thread terminates. |
| </li> |
| <li> |
| Otherwise, the following happens: |
| <ul> |
| <li> |
| The stack frame that caused this method invocation becomes valid. This |
| includes all its registers and their old values. |
| </li> |
| <li> |
| Execution continues at the bytecode instruction immediately following |
| the invoke-kind or invoke-kind/range instruction that caused this method |
| invocation. |
| </li> |
| </ul> |
| </li> |
| </ul> |
