This is because Javadoc needs to know the exact location of the class you are referencing in order to link to it. Just add the package as mentioned in the comment above.
@see mypackage.MyClass
The javadoc tool will allow you to use shortcuts as follows:
@see #Constructor(Type1 p1, Type2 p2)
@see MyClass#Constructor(Type1 p1, Type2 p2)
, :
@see mypackage.MyClass
:
. : MyClass.Constructor(Type1 p1, Type2 p2)
