22:46 <kalenp[m]> Hello JRuby folks. Your friends at Looker here again 🙂. We're running into a heisenbug that we can't quite pin down and now we're off in the weeds looking at potential jruby issues. Anybody available to talk it through so we can eliminate this possibility or not?

22:53 <kalenp[m]> Basically, we're getting parse errors from the json-jruby module on what appears to be well-formed json. It only shows up intermittently in production, but once it begins it seems to affect a server until we reboot the process. We're not 100% sure, but this seems to be correlated with our upgrade from java 8 to java 11.

22:54 <kalenp[m]> One of the long-shot theories is some sort of string encoding issue, or perhaps something threading related, but we don't have a lot to back that up. Hoping that somebody here might be able to point us at some more details to investigate along those lines.
