环境信息
  • arthas-boot.jar 或者 as.sh 的版本: 3.6.3
  • Arthas 版本: 3.6.3
  • 操作系统版本: macos m1
  • 目标进程的JVM版本: xxx
  • 执行arthas-boot的版本: xxx
重现问题的步骤

使用openj9并启用-Xgcpolicy:balanced的gc策略,在arthas attach之后执行dashboard报错

[arthas@73192]$ dashboard
process dashboard failed: init argument cannot be less than -1
期望的结果

能够正常使用dashboard

实际运行的结果

实际运行结果,最好有详细的日志,异常栈。尽量贴文本。 查阅日志报错如下:

怀疑是和openj9的兼容问题 注:当openj9使用默认gc策略时无此报错

openjdk8 也有类似问题

illegalArgumentCount:  1, number is: -185642, need >= 2
illegalArgumentCount:  2, number is: -113641, need >= 2
illegalArgumentCount:  3, number is: -156348, need >= 2
illegalArgumentCount:  4, number is: -43872, need >= 2
56921=56921
27821=43*647
183535=5*11*47*71
illegalArgumentCount:  5, number is: -151189, need >= 2

目前只保证支持 openjdk 系列。

这是math-game demo项目的输出
