I know it should be the responsibility of my Max object to check outlet indexes, but I just got burned by this *again* so here we go...
Steps to Reproduce:
1. Build this MXJ max object:
import com.cycling74.max.MaxObject;
public class crash extends MaxObject {
public void bang() {
outlet(2, "goodbye");
}
}
2. Create this patch:
#P button 93 63 15 0;
#P newex 93 88 56 196617 mxj crash;
#P connect 1 0 0 0;
3. Click the button. Max crashes.
Expected behavior:
Do not crash! Print an error to the Max window indicating an invalid outlet index was used.
