FULL PRODUCT VERSION :
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) Client VM (build 14.2-b01, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
Compiler fails to infer the correct type of a wildcard capture.  Given a class A<T extends A<T>> with a method T get(), the compiler should be able to infer that the return type when calling get() on an instance of A<?> is <T extends A<T>>.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
javac Test.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Successfully compiles.
ACTUAL -
Compile fails with error:

Test.java:10: <T>f1(T) in Test cannot be applied to (Test.A<capture#282 of ?>)
    f1(obj.get()); // Fails to compile

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
public class Test {
  class A<T extends A<T>> {
    T get() {return null;}
  }
  
  <T extends A<T>> void f1(T t) {}
  <T extends A<?>> void f2(T t) {}
  
  void main(A<?> obj) {
    f1(obj.get()); // Fails to compile
    f2(obj.get()); // Works
  }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Use method f2 instead of f1.
