>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.
