[JBoss-user] [Javassist user questions] - Re: javassist tries to call a method with wrong return type
And it fails only if the return type of the method is String, all other return types seems to work (for example java.util.Locale, Object, my own classes, etc...)!

[JBoss-user] [Javassist user questions] - javassist tries to call a method with wrong return type
Hello,
I get the following exception:
Exception in thread "main" java.lang.NoSuchMethodError:
mycompany.Type.getValue()Ljava/lang/String;
mycompany.Type is only
public interface Type
{
Object getValue();
}
The generated javassist method body is the following:
{
mycompany.Type type = getType();
Object value = type.getValue();
return ($r)value;
}
the return type of the method is String, so ($r) should do a cast to String.
Where is the error?
Why tries Javassist to call the getValue()Ljava/lang/String method instead of
getValue()Ljava/lang/Object
?
Thanks,
Norbi

[JBoss-user] [Javassist user questions] - javassist.NotFoundException: java.lang.Object - with securit
Hello,
When I run Javassist 2.6 (in Tapestry 3.0) without security manager, everthing works
OK.
But when I switch to a security manager it throws a NotFoundException: java.lang.Object
I debugged the code and I figured out that
getClass().getResourceAsStream("/java/lang/Object.class")
returns null when using the security manager.
What permissions should be set to prevent this error?
Thanks,
Norbi
