Dm: Method invokes inefficient new String() constructor (DM_STRING_VOID_CTOR)


Dm: Method invokes inefficient new String() constructor (DM_STRING_VOID_CTOR)
 Creating a new java.lang.String object using the
  no-argument constructor wastes memory because the object so created will
  be functionally indistinguishable from the empty string constant
  "".  Java guarantees that identical string constants
  will be represented by the same String object.  Therefore,
  you should just use the empty string constant directly.
