transmittable-thread-local的JavaAgent报ClassCircularityError错误，含可复现代码

linfan commented 3 years ago

与 #234 应该是同一个问题，2.12.1版本在Mac下可复现。

复现代码

https://github.com/linfan/transmittable-thread-local-issue-278

JVM版本

$ java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

复现步骤

直接在代码根目录执行./gradlew clean build --info，即有一定概览会出现。

可反复执行多次，一般三次以内至少会出现一次ClassCircularityError异常。报错的堆栈会有两种情况，其中第二种情况出现的概率比较高。

第一种情况，报LinkedHashMap.java:533的位置：

其他信息

只在Gradle下出现，使用Maven构建不会有此异常
修复建议，在JavaAgent的Processor里直接忽略 java.util 包吧，这个包里本来也没有线程池

PS：这个问题不影响使用，只是运行测试的时候会打印个异常，然后实际结果一切正常；不紧急。

oldratlee commented 3 years ago

非常专业的问题说明（包含复现代码工程） @linfan 👍 ❤️

想进一步挖一下，以更完整分析深入些解决这个问题。原因如下：

2. 修复建议，在JavaAgent的Processor里直接忽略 java.util 包吧，这个包里本来也没有线程池

从目前出现ClassCircularityError的case来看，是在 java.util 包；如果没有进一步确定原因，忽略 java.util 包后，其它包可能接着会再次成为问题项。
TTL Agent的扩展机制正在开发中，以允许业务写扩展；扩展Agent功能不期望有包被（Hard-Code）忽略/跳过。

@linfan 有空方便一起分析原因以进一步解决吗？ 😃

window10环境，jvm版本

java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

我在cmd中使用

java -Dfile.encoding=utf-8 \
  -Xbootclasspath/a:C:/mvn_repository/com/alibaba/transmittable-thread-local/2.12.1 \
  -javaagent:C:/mvn_repository/com/alibaba/transmittable-thread-local/2.12.1/transmittable-thread-local-2.12.1.jar \
  -jar hello-1.0.0.jar

命令启动jar包也遇到了类似的循环依赖的问题；

变更transmittable-thread-local版本为2.10.2，便不会再命令行遇到这个错误；在idea中配置2.12.1版本或者2.10.2的上述同样的vm options，也没有遇到循环依赖的错误。

@linfan @xyc0123456789 发布了v2.12.3 https://github.com/alibaba/transmittable-thread-local/releases/tag/v2.12.3

包含这个问题的修复；可以试试是不是解决问题了？ ❤️

PS： https://github.com/linfan/transmittable-thread-local-issue-278 在我MAC开发机Java 8 (1.8.0_312)上N次运行，没复现出来 😅 可能和操作系统WINDOWS 或 Java的小版本有关系。

# My java version
$ java -version
openjdk version "1.8.0_312"
OpenJDK Runtime Environment Corretto-8.312.07.1 (build 1.8.0_312-b07)
OpenJDK 64-Bit Server VM Corretto-8.312.07.1 (build 25.312-b07, mixed mode)

刚刚验证了一下，2.12.3没有再出现前面的循环依赖的问题了。

我注意到在之前的环境下，cmd中使用

java -Dfile.encoding=utf-8 
-Xbootclasspath/a:C:/mvn_repository/com/alibaba/transmittable-thread-local/2.12.1 
-javaagent:C:/mvn_repository/com/alibaba/transmittable-thread-local/2.12.1/transmittable-thread-local-2.12.1.jar 
-jar mdc-ttl-server-1.0-SNAPSHOT.jar

命令启动会出现循环依赖，而

java -Dfile.encoding=utf-8  
-javaagent:C:/mvn_repository/com/alibaba/transmittable-thread-local/2.12.1/transmittable-thread-local-2.12.1.jar 
-jar mdc-ttl-server-1.0-SNAPSHOT.jar

去掉了-Xbootclasspath选项就不会出现循环依赖的错误

@xyc0123456789 谢谢你的验证。👍

去掉了-Xbootclasspath选项就不会出现循环依赖的错误

TTL从v2.6.0开始，加载TTL Agent时会自动设置TTL Jar到boot class path上；可以不需要为TTL添加-Xbootclasspath JVM参数。 @xyc0123456789

注意：不能修改从Maven库下载的TTL Jar文件名（形如transmittable-thread-local-2.x.y.jar）。如果修改了，则需要自己手动通过-Xbootclasspath JVM参数来显式配置（就像TTL之前的版本的做法一样）。

更多参见文档

@oldratlee 问题修复了，出现问题的根本原因可以分享说明下吗？

alibaba / transmittable-thread-local

transmittable-thread-local的JavaAgent报ClassCircularityError错误，含可复现代码 #278
