Issue with rJava module loading in the platform

[LanceJensen-General]

One of our users was utilizing our hit tracking solution on KM. The url is https://rcloud.web.att.com/shiny.html?notebook=5628a8ac9c9ccf42480bcd60d8e0cef9&redirectToNotebook=e168bcbe5ee1fee910b4f2b5255b694b

The platform is throwing a library import error for rJava for anonymous users. The console trace of the error is below:

Please advise.

I get the same error if I'm logged in or logged out, so I don't think it has to do with anonymous users.

I guess it is probably a configuration problem on the server.

Could you please file a ticket, or email me and I will forward to the appropriate people? It's clearly not an error in rcloud.shiny itself (as rcloud.shiny doesn't use rJava).

[LanceJensen-General]

Ok I will file the ticket. I do not use rJava in any of my dependencies but I assumed it was part of the platform when I saw the source errors. I will forward you the ticket after I place it.

Thanks.

My guess - someone upgraded Java an didn't run sudo R CMD javareconf

[gordonwoodhull]

Thanks @s-u.

@LanceJensen-General, it's probably the gateKeeper package that triggered this.

[LanceJensen-General]

Ok. I will go and add that feedback to the ticket.
