[ BUILD # : 201112012200 ]
[ JDK VERSION : 1.7.1 ]

Consider the following class:

class MyClass<T> {
    Map<Map<?, ?>, ?> myMap = new HashMap<Map<?, ?>, Object>();
    
    Set<Map<? super T, ?>> getLists() {
        return myMap.keySet();|
    }
    
    void assignLists() {
        Set<Map<? super T, ?>> lists = myMap.keySet();|
    }
}


Observed Behaviour

Pressing Ctrl-Enter (show hints) at the first carat position shows one hint:

        "Change method return type to Set>" (note the trailing angle bracket)

Invoking the hint changes the first method signature as follows:

        Set<Map< ?,   ?>> getLists() {  (note the spaces inside the angle
brackets)


Pressing Ctrl-Enter (show hints) at the second carat position shows one hint:

        "Change type of lists to Set<Map<?,?>>"

Invoking the hint changes the variable assignment in the second method
signature as follows:

        Set<Map< ?,       ?>> lists = myMap.keySet();  (note the spaces inside
the angle brackets)




Expected Behaviour:

The first hint should read something like "Change method return type to
Set<Map<?, ?>>" (adding the type argument of Set), and produce the same code
but without extra spaces within the angle brackets (i.e.  the method signature
should be "Set<Map<?, ?>> getLists() {" ). The second hint should produce the
same code but without the angle brackets (i.e. the variable assignment should
be " Set<Map<?, ?>> lists = myMap.keySet();")
