>Description:
When invoking a native method, the evaluation order of argument lists are not guaranteed (Java's methods are OK).

For example:

class XX {
  void foo( int a, int b ) {..}
  native void bar( int a, int b );
  void test() {
    int x = 0;
    foo( x, x += 1 );
    x = 0;
    bar( x, x += 1 );
  }
}

foo receives a=0, b=1
bar receives a=1, b=1 (in my environment)

See Java Languange Specification (2nd Edition) Sec. 15.7.4.
