环境信息
  • arthas-boot.jar 或者 as.sh 的版本:3.6.6
  • Arthas 版本: 3.6.6
  • 操作系统版本: macos m1
  • 目标进程的JVM版本: openj9-jdk8
  • 执行arthas-boot的版本: openj9-jdk8
重现问题的步骤
  1. 使用openj9启动应用
  2. 使用openj9启动arthas-boot并attach对应进程
  3. 执行classloader -t找到对应classloader
  4. 执行classloader -c d837015e --load org.springframework.boot.SpringApplication
  5. 执行trace org.springframework '#cost > 1000'
  6. 报错
期望的结果

正常输出trace

实际运行的结果
[arthas@22508]$ trace org.springframework* * '#cost > 1000'
Affect(class count: 4180 , method count: 33388) cost in 28438 ms, listenerId: 1

怀疑arthas对于openj9的支持存在问题

  • 假如可以,请给我们一个demo应用,方便排查问题

应用本身没有特殊,使用springboot应用应该都能够复现问题。主要应该是和OpenJ9虚拟机本身有关。我使用的jar包方式启动,因此类加载器是org.springframework.boot.loader.LaunchedURLClassLoader

我的openj9版本号是

openjdk version "1.8.0_362"
IBM Semeru Runtime Open Edition (build 1.8.0_362-b07)
Eclipse OpenJ9 VM (build v0.36.0-release-c5da55ccc, JRE 1.8.0 Mac OS X amd64-64-Bit Compressed References 20230113_599 (JIT enabled, AOT enabled)
OpenJ9   - c5da55ccc
OMR      - 2bb04132e
JCL      - 1a94e3037e based on jdk8u362-b07)

我们这里用的IBM WEBSPHERE系统也是ibm的jdk,arthas没法使用。

目前只支持 openjdk 系列的。
