Bug 322497

We could add a code style problem for an invocation of a varargs method with unnecessary "new Type[] {..}" right in the arguments list.

Example:
public class Try {
    public static void main(String[] args) {
        foo("x", "1", "1");
        foo("x", 1);
        foo("x", "a", "b");
        
        // add a problem for these two:
        foo("x", new String[] {"a"});
        foo("x", new Object[] {"a", "b"});
    }
    
    static void foo(String first, Object... o) {
        System.out.println(o.getClass());
    }
}

JDT/UI can then add a quick fix to remove the unnecessary explicit array creation. The quick fix should also work in the 'new String[] {"a"}' case in the example, although there's another problem reported there.
