Quitting jshell extremely slow on my Mac

[Weijun Wang]

Quitting jshell with /exit or Ctrl-D is extremely slow here. It just wait for about half a minute and then quit.

If I create a brand new user and run jshell there, it quits immediately. I don't think I've created any startup scripts for jshell for my own user. "find . | grep jshell" in $HOME shows nothing interesting.

Here is a gist of jstack outputs. There are 2 processes. I took once before Ctrl-D (line 426), and multiple times after it.

I'm using fastdebug build 14-ea+24-1107 and I'm on macOS 10.14.6.

What could be the problem?

Thanks in advance,
