 /**
  * Hacky fix for poor javac 6 literal parsing. javac 6 doesn't set the AST node start position
  * correctly when a numeric literal is preceded by -. So we scan the source backwards starting at
  * the provided start position, looking for whitespace, until we find the true start position.
  * javac 7 gets this right.
  *
  * @return The actual start position of the literal. May be the same as the start position given
  *     by the tree node itself.
