### Version

1.1.2

### Installation Type

Official Docker Compose

### Service Name

DongTai-agent-java

### Describe the details of the bug and the steps to reproduce it

When using resttemplate to customize the header, some fields will not be loaded, such as the host header.In sun.net.www.protocol.http.httpurlconnection, allowrestrictedheaders is assigned in the static block and will be initialized only once. In the agent, httpurlconnection is loaded before the program, which leads to this problem.
使用RestTemplate自定义头的时候有些字段会加载不进来，比如说host头。因为在sun.net.www.protocol.http.HttpURLConnection中allowRestrictedHeaders是放在static块中赋值，只会初始化一次。而在agent中先于程序加载了HttpURLConnection，所以导致这个问题。
