SpotBugs检查待修复问题-Malicious code vulnerability-Mehtod returning array may expose internal representatation

[YOC19970520]

类型：Malicious code vulnerability-Strong reference to mutable object

描述：This code stores a reference to an externally mutable object into the internal representation of the object. If instances are accessed by untrusted code, and unchecked changes to the mutable object would compromise security or other important properties, you will need to do something different. Storing a copy of the object is better approach in many situations.
