HEAD, follow-up to bug 322817

The JavaCore.COMPILER_PB_UNAVOIDABLE_GENERIC_TYPE_PROBLEMS option misses references in conditional expressions.

In the example below, generifying Project#getOptions() gets rid of the type safety warning, and the compiler option should also hide it.


package problems;
import java.util.Map;

public class Project {
    //raw return type (assume in 1.4 code)
    public Map/*<String, String>*/ getOptions(boolean b) {
        return null;
    }
}

package problems;
import java.util.Map;

public class GenericConditional {
    void foo(Project project) {
        // Bad warning: "Type safety: The expression of type Map needs
        //    unchecked conversion to conform to Map<String,String>"
        Map<String, String> options=
                        project != null ? project.getOptions(true) : null;
        System.out.println(options);
    }
}
