16:07 <Serah_Eley> Without digging in too much deeper yet, just from the class names in the trace, my guess is that Amazon's Linux image or Java runtime isn't setting whatever JNR Constants needs to recognize the platform correctly. Either that, or the restricted file write permissions (only writing to /tmp is allowed) are making some test or other fail.

16:08 <Serah_Eley> Can anyone help me understand this error better, and hopefully suggest a fix or workaround? If it's a matter of setting some environment variable or system property, I can do that.

16:10 <Serah_Eley> (For the record, I tried downgrading to JRuby 9.1.17.0 and it simply failed more silently, with a no-details error at org.jruby.Ruby.init.)

16:12 <Serah_Eley> Thanks in advance for any help you can offer. I've already put multiple woman-weeks of effort into just getting this far, and I'll be heartbroken if I have to rewrite our business code in something other than Ruby!

16:19 <Serah_Eley> (...Blargh. Looking back at the logs, I think the IRC server may have removed my first few lines describing what I was asking for help with, because I pasted in a stacktrace and it seems to think that was spam. Nutshell is, I'm trying to run JRuby 9.2.0 in AWS Lambda on the Java8 runtime, and I'm getting a "Could not load platform constants for OpenFlags" error on initialization.)

16:23 <enebo> Serah_Eley: if you can nightly something may have been fixed. I know some jnr-constant releases have been updated on upcoming 9.2.1.0. grab https://projectodd.ci.cloudbees.com/view/JRuby/job/jruby-development-dist/lastBuild/artifact/release/

16:25 <Serah_Eley> Oh, excellent. I hadn't thought to look forward yet. Thank you! I'll try that right away and report back on whether it works or not!

16:26 <enebo> Serah_Eley: we have went way too long without putting out 9.2.1.0 too so a lot has been fixed

16:28 <Serah_Eley> I appreciate it. I did a lot of looking into whether anyone had examples of recent JRuby running in Lambda, and only found a couple of examples from much older versions. Given the Java hurdles I had to figure out to make it this far, I'm no longer surprised...

18:26 <Serah_Eley> Hi again... So at enebo's suggestion, I embedded the 9.2.1.0 nightly into my shadow jar and tried the AWS Lambda test again. I got the same "Could not load platform constants for OpenFlags" error.

18:26 <Serah_Eley> Same stacktrace, just slightly different line numbers at OpenFlags.java and RubyFile.java: https://gist.github.com/SFEley/468520d54e0761c15783ec5fc2bd286d

18:28 <Serah_Eley> I'm going to submit a JRuby bug now, but any other tips or ideas will be appreciated. Thank you!

21:35 <enebo> lopex: sweet

21:36 <enebo> lopex: web assembly will succeed in way java never did on the browser

21:36 <enebo> lopex: they have benefit of hindsight as well as being from browser incumbents

21:36 <lopex> enebo: yeah, there's already some quite impressive tools
