Given below annotated code:
import dataflow.qual.DataFlow;
public class TestUpperBound3 {
public @DataFlow(typeNames={"java.lang.Integer","java.lang.String"}) Object upperBoundTesting3(int c) {
if (c > 0) {
return 3;
}
return "I am a String!";
}
}
under java 7, using typecheck
mode type checking above annotated code would result in an error:
TestUpperBound3.java:6: error: [return.type.incompatible] incompatible types in return.
return 3;
^
found : @DataFlow(typeNames="int") int
required: @DataFlow(typeNames={"java.lang.Integer", "java.lang.String"}) Object
1 error
However, the same annotated code would pass the type checking under java 8.
Do you meet similar errors before? Any ideas about what is the possible reasons of why this happens would be appreciated!
Thanks!
