Does't compatible with JFinal framework

[pepeshore]

Describe the bug

JFinal is a Web and ORM framework。 when I add VM option -javaagent:opentelemetry-javaagent.jar, all HTTP requests result in a 500 error.

Steps to reproduce

1.git clone https://github.com/pepeshore/jfinal-demo this is a simple jfinal demo

2. Open this project with IDEA(may be eclipse works too )
3. Run jfinal.MyApp#main with VM options VM option -javaagent:opentelemetry-javaagent.jar added
4. Exec command curl -v http://127.0.0.1:8082/jfinal/hello

Expected behavior

http status code is 200

Actual behavior

http status code is 500

Javaagent or library instrumentation version

2.4

Environment

JDK: openjdk version "1.8.0_322" OpenJDK Runtime Environment (Zulu 8.60.0.21-CA-macos-aarch64) (build 1.8.0_322-b06) OpenJDK 64-Bit Server VM (Zulu 8.60.0.21-CA-macos-aarch64) (build 25.322-b06, mixed mode) OS: mac

Additional context

No response

[pepeshore]

It seems to be that JFinal will put all the attributes of a request into map, and then use FastJson to serialize the map. shown as below

And in tomcat instrumentation, two key named io.opentelemetry.javaagent.instrumentation.servlet.ServletHelper.AsyncListenerResponse and io.opentelemetry.javaagent.instrumentation.servlet.ServletHelper.Context will be added into a request, which are not serializable, and will throw exceptioon when serialize them. the exception stack is shown below com.alibaba.fastjson.JSONException: write javaBean error, fastjson version 1.2.69, class org.apache.catalina.connector.Response, fieldName : io.opentelemetry.javaagent.instrumentation.servlet.ServletHelper.AsyncListenerResponse, write javaBean error, fastjson version 1.2.69, class org.apache.catalina.core.StandardContext, fieldName :

We use request attributes to associate some of our own state with the request. You can work around this by excluding these attributes

JsonRender.addExcludedAttrs(
  "io.opentelemetry.javaagent.instrumentation.servlet.ServletHelper.AsyncListenerResponse",
  "io.opentelemetry.javaagent.instrumentation.servlet.ServletHelper.Context",
  "trace_id",
  "span_id");

[pepeshore]

It works. And do we has plan to support jfinal? auto excluded attrs above and get http.route

We'd welcome a contribution for this
