Dear Konstantin,
I think I have encountered a (weird) JEL bug.
If I compile and run the following program against (e.g.) JEL 2.1.1:
import gnu.jel.Evaluator;
import gnu.jel.Library;
public class Jelly3 {
public static void main(String[] args) throws Throwable {
Library lib = new Library(new Class[] {Jelly3.ALib.class},
null, null, null, null);
// These calls work OK:
Evaluator.compile("dx==1", lib, null);
Evaluator.compile("dx==1", lib, Boolean.class);
Evaluator.compile("ix==1", lib, null);
// But this one causes a java.lang.VerifyError:
Evaluator.compile("ix==1", lib, Boolean.class);
}
public static class ALib {
public static double dx() {
return 1.0;
}
public static int ix() {
return 1;
}
}
}
I see this error:
Exception in thread "main" java.lang.VerifyError: (class: dump, method:
evaluate signature: ([Ljava/lang/Object;)Ljava/lang/Object;) Expecting to find
unitialized object on stack
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2671)
at java.lang.Class.getConstructor0(Class.java:3075)
at java.lang.Class.newInstance(Class.java:412)
at gnu.jel.Evaluator.compile(Evaluator.java:158)
at Jelly3.main(Jelly3.java:16)
Any ideas?
Many thanks,
Mark
