scala pattern matching can't handle "NaN","NegativeInfinity " etc.
in GenerateUtils, CodeGenerator, some code logic fall into this issue, please
refer to
the screenshot for details.
{code:java}
def main(args: Array[String]): Unit = {
val floatVaue = Float.NaN
floatVaue match {
case Float.NaN => println("Float.NaN")
case Float.NegativeInfinity => println("Float.NegativeInfinity")
case _ => println("not match")
