[chef] Re: Noob Alert: languages attribute?

[Avishai Ish-Shalom < >]

I've encountered this and other java identification bugs before. I
worked around them by writing my own function for java flavor
identification, but i'm not a java man and I doubt my function will work
with the multitude of java versions out there.

This is a bug in Ohai and should be fixed. I'll check if there are any
open tickets, but we need someone who can test against as many JVMs as
possible.

Regards,
Avishai
