Compiler issuses [unchecked] warning without line number for anonymous inner classes.

Tried on Solaris JDK build 1.6.0-ea-b35.

Please see the following code
<code>
class Pair<X,Y> {
      Pair(X x) {
      }
      <X> void testMethod(X x) {
          Pair<String,String> y = new Pair("Hi Pair") {};
      }
}
</code>

Output when compiled:
<output>
bash-2.05b$ $b/javac -Xlint Test31.java
Test31.java:5: warning: [unchecked] unchecked call to Pair(X) as a member of the raw type Pair
          Pair<String,String> y = new Pair("Hi Pair"){};
                                  ^
[unchecked] unchecked call to Pair(X) as a member of the raw type Pair
Test31.java:5: warning: [unchecked] unchecked conversion
found : <anonymous Pair>
required: Pair<java.lang.String,java.lang.String>
          Pair<String,String> y = new Pair("Hi Pair"){};
                                  ^
3 warnings
</output>
The second warning doesn't have line number and its duplicate of first.
