As I said at runtime "same package" means "same package name" AND "same classloader" or at least this is my interpretation of the jvm spec, so if you have two different classloaders loading your two classes like you said, they're not considered to be in the same package. In the Java version evidently there's only one classloader involved. Alessio -- You received this message because you are subscribed to the Google Groups "JVM Languages" group.
