      Description

      i define a udf with variable paramater in Smalls.java like
          public static String variableParameterFunction(String... strings) {
            String result = "";
            if (strings == null) {
              return  result;
            }
            for (String s : strings) {
              result += s;
            }
            return result;
          }
      

      then i use it in UdfTest.java

      with.query("select \"adhoc\".\"variableParameterFunction\"('test', 'test')").returns("EXPR$0=testtest\n");
      
      will get the following error
      ava.lang.RuntimeException: exception while executing [select "adhoc"."variableParameterFunction"('test', 'test')]
