Is this still available? I tried in 1.6.5.1, and it looks like the option was changed to --jdb in the usage, but this response with: "jruby: unknown option --jdb"

Hi, Matt,

Do you use jruby-launcher?

I think that the flag was meant for shell script:

$ ./bin/jruby.sh  --jdb
Initializing jdb ...
>

I think that the launcher would have to know about this flag, and act accordingly, but obviously that's not happening. Since this is a regression of sorts, could you open a separate ticket?

Thank you.

Hmm, it appears this is an issue with rvm, then, and how it is installing. I switched to the jruby binary from jruby.org and it works fine now.

Thanks.

It looks like we're missing the --jdb flag in the JRuby native launcher, which rvm installs by default. I'll look into that.

Wow, I gave it a shot but I cannot figure out the right way to wire it into the launcher. If someone else wants to give it a shot, be my guest: https://github.com/jruby/jruby-launcher.
