A DESCRIPTION OF THE PROBLEM :
package aaa
import org.springframework.core.ParameterizedTypeReference;
public class Bug {
public static class Pojo{
}
public static class GenericPojo<T>{
}
public GenericPojo<Pojo> getPojo(){
// GenericPojo<Pojo> gp = doGet(new ParameterizedTypeReference<GenericPojo<Pojo>>() {});
GenericPojo<Pojo> gp = doGet(new ParameterizedTypeReference<>() {});
return gp;
}
public static <T> T doGet(ParameterizedTypeReference<T> typeReference){
return null;
}
}
REGRESSION : Last worked in version 10.0.2
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
create a spring project and insert a new class, which use ParameterizedTypeReference
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
compile success
ACTUAL -
