上古 shell 代码啊，有计划用 Java 重写么？

I guess I left a patch on Gitlab before leaving Alibaba, possibly in the personal organization `chuansheng.lcs/`, can anybody from Alibaba please help to check if the patch is still...

- crash在GC里，试试换CMS GC看还会不会crash？JVM选项 `-XX:+UseConcMarkSweepGC`, 详细文档 https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/cms.html - 日志里有“/tmp/libio_grpc_netty_shaded_netty_transport_native_epoll_x86_648524811594714692156.so (deleted)” 之类的，是不是使用了某种“热”更新或动态代码加载技术？这类技术有已知的风险，能关掉试一试吗？ ps: 解出来的crash指令似乎有问题 http://shell-storm.org/online/Online-Assembler-and-Disassembler/?opcodes=ab+bc+00+80+38+00+0f+84+1f+03+00+00+48+8d+05+51%0D%0Ac1+ba+00+41+8b+7a+08+8b+48+08+48+d3+e7+48+03+38%0D%0A8b+4f+08+81+f9+00+00+00+c0+0f+8c+fe+03+00+00+83%0D%0Af9+00+0f+8e+10+04+00+00+f6+c1+01+0f+85+08+03+00+&arch=x86-64&endianness=little&dis_with_addr=True&dis_with_raw=True&dis_with_ins=True#disassembly

尝试缩小问题范围看看是不是热更导致的吧；可以考虑尽量使用 jdk 规范支持的一些标准机制，不要做太tricky的事情。

Thank you, Sanhong! Looking forward to the evaluation progress :)

@joeyleeeeeee97 I think this issue looks more like an enhancement / feature request than a mere question. Can we change the label to 'enhancement'?

相关信息应该不是很多吧，为什么要隐藏呢？ 使用某个特性的时输出相关信息不是很方便线上排查问题么

> 我这边程序有个需要交互的控制台，elesticheap的输出经常把有用的信息或者界面冲掉 @mmyxym 可能会有一些输入 :)
