When the compiler encounters a varargs method, it translates thevarargs formal parameter into an array. However, the Javaprogramming language does not permit the creation of arrays ofparameterized types. In the methodArrayBuilder.addToList, the compiler translates thevarargs formal parameter T... elements to the formalparameter T[] elements, an array. However, because oftype erasure, the compiler converts the varargs formal parameter toObject[] elements. Consequently, there is apossibility of heap pollution. See the next section, Potential Vulnerabilities of Varargs Methodswith Non-Reifiable Formal Parameters, for more information.
