[alibaba/fastjson]v1.2.37到v1.2.44 反序列化成自定义类对象时，Double、Float类型的变量会自动初始化为0.0(json字符串对应值为null)

sonStr={"age":null,"ftest1":null,"id":null,"name":null,"test1":null,"test2":null}

类： public class Person implements Serializable { private String id; private String name; private Integer age; private Double test1; private Double test2; private Float ftest1;

public String getId() { return id; }

public void setId(String id) { this.id = id; }

public String getName() { return name; }

public void setName(String name) { this.name = name; }

public Integer getAge() { return age; }

public void setAge(Integer age) { this.age = age; }

public Double getTest1() { return test1; }

public void setTest1(Double test1) { this.test1 = test1; }

public Double getTest2() { return test2; }

public void setTest2(Double test2) { this.test2 = test2; }

public Float getFtest1() { return ftest1; }

public void setFtest1(Float ftest1) { this.ftest1 = ftest1; } }

反序列化后 test1=0.0, test2=0.0, ftest=0.0

这不太合理吧，确认下这个是bug还是增加的新特性
