The problem here.. given in the method declaration. If you really want the inference one possible workaround is to do something like this Pair extends..
Java generics - Make Generic to extends 2 interfaces http://stackoverflow.com/questions/13101991/java-generics-make-generic-to-extends-2-interfaces question concerns I'd like to further point out that type inference would theoretically cause such bounds to be pointless anyway...
How do generics of generics work? http://stackoverflow.com/questions/16449799/how-do-generics-of-generics-work the operation isn't unsafe it's just a victim of limited inference . If it were unsafe the above wouldn't compile. Since using.. it being required here is a technical limitation of the inference engine. Indeed the Java 8 compiler is currently slated to ship.. is currently slated to ship with many improvements to type inference . I'm not sure whether your specific case will be resolved...
How does the code behave different for Java and C compiler? http://stackoverflow.com/questions/1788696/how-does-the-code-behave-different-for-java-and-c-compiler has the post decrement has no influence. Also there is no inference between the two operators using them both in the same expression..
Compilers behave differently with a null parameter of a generic method http://stackoverflow.com/questions/3000177/compilers-behave-differently-with-a-null-parameter-of-a-generic-method annotated for clarity Bug ID 6299211 method type variable inference broken for null This program does not compile public class Try..

Collections.emptyList() returns a List<Object>? http://stackoverflow.com/questions/306713/collections-emptylist-returns-a-listobject use EMPTY_LIST as opposed to emptyList java generics type inference share improve this question The issue you're encountering.. out the generic type parameters for you. It's called type inference. For example if you did this public Person String name List..
Java compile speed vs Scala compile speed http://stackoverflow.com/questions/3490383/java-compile-speed-vs-scala-compile-speed compiler is more sophisticated than Java's providing type inference implicit conversion and a much more powerful type system. These..
Reference is ambiguous with generics http://stackoverflow.com/questions/5361513/reference-is-ambiguous-with-generics Parameter V Parameter R Field V R The result is R V per inference rules in 15.12.2.7 Now we substitute R and check subtype relations.. Per 15.12.2.2 to see if m1 is applicable for s4 first type inference is carried out to the conclusion that R T then we check Ai Si..
Why can't you have multiple interfaces in a bounded wildcard generic? http://stackoverflow.com/questions/6643241/why-cant-you-have-multiple-interfaces-in-a-bounded-wildcard-generic still works. One trouble I know would be in the type inference. The current inference rules simply can't deal with interception.. trouble I know would be in the type inference. The current inference rules simply can't deal with interception types. There's no.. A B C . If we reduced it to A C or A B any current inference engine has to go through major overhaul to allow such bifurcation...
