#63 polymorphism with hotspot/classic differ

[Anonymous]

Having a script like:

//startscript///////////////////
perform(Callback callbackobject){
callbackobject.install(super);
}
//return (Sub1)this; //switch between the two types..
return (Sub2)this;
//startscript///////////////////

and the classes:

public class Callback {
public void install(Sub1 s){
System.out.println("install(Sub1)");
}
public void install(Sub2 s){
System.out.println("install(Sub1)");
}
}

public class Base{
//...
}
public class Sub1 extends Base{
//...
}
public class Sub2 extends Base{
//...
}

running the script in jdk1.3.0-classic gives correct
output.
running the same in jdk1.3.0-hotspot sometimes takes
wrong install-method!
workaround is to cast return-value to the correct Type:

//startscript///////////////////
perform(Callback callbackobject){
callbackobject.install((Sub2)super);
}
return (Sub2)this;
//startscript///////////////////

...which is not really bad.

The fact that beanshell (or java) behaves different
in -classic mode is really ugly, since we develop in
classic mode cause of the debuggers slow speed with
hotspot.
