If true, then that kind of method really does not exist because this method returns some Collection. But on the other hand if I call this method, I'm not assigning its return value to any variable. I just call this method like this: service.doSmth(); Any ideas why this error occurs?

Thanks. no such Campbell Ritchie Sheriff Posts: 50644 83 posted 7 years ago Don't know. Please supply more details. Are the two classes in the same package and same .jar?

So any additions to a supplier class which your recompiled class has as a dependency may not be implemented in the .class file.
