jlaskey@3:  * NASHORN-703
jlaskey@3:  *
jlaskey@3:  * Self modifying assignments and ++/-- operators had two issues
jlaskey@3:  * 1) the base was loaded twice
jlaskey@3:  * 2) if the base was anything but an IdentNode, AccessNode or IndexNode and in the scope, it would
jlaskey@3:  *    only be evaluated once, leading to bytecode stack underflow
jlaskey@3:  *
jlaskey@3:  * This file is split into two tests as the presence of eval affects the whole script
jlaskey@3:  *
jlaskey@3:  * @test
jlaskey@3:  * @run
