| 25 * NASHORN-703 | |
| 26 * | |
| 27 * Self modifying assignments and ++/-- operators had two issues | |
| 28 * 1) the base was loaded twice | |
| 29 * 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would | |
| 30 * only be evaluated once, leading to bytecode stack underflow | |
| 31 * | |
| 32 * This file is split into two tests as the presence of eval affects the whole script | |
| 33 * | |
| 34 * @test | |
| 35 * @run | |
