Subject Start shell/REPL without launching java monitor?
Date Fri, 12 Oct 2018 02:54:22 GMT
Hi Groovy community,

I am new to Groovy and when running `groovysh` with "3.0.0-alpha-3, JVM:
1.8.0_171" on macOS, I see a, hmm, Java monitor(?), named "GroovyShell"
launched.

If I kill it, process `groovysh` quit with exception below. I'd like to
know if we can suppress the launch of "GroovyShell" process. It switch the
focus of cursor and quite annoying for me.

Best,
tison.

Type ':help' or ':h' for help.
