Description

hi,I used to NumberUtils.isNumber()[version:3.6] find this error, this error is mainly caused by method isCreatable() in the 723 line of code。
See below for details:

String str = "0927";
System.out.println(NumberUtils.isNumber(str));
//result:false

String str1 = "9027";
System.out.println(NumberUtils.isNumber(str1));
//result:true
