Looking through netty's source, it looks like this exception is emitted here.

Tried again with Oracle JDK 11, got the same error:

@siddharthteotia @pravindra do you know what this might be about? I haven't seen this issue myself

[asfimport]

Wes McKinney / @wesm:
It's possible this is fixed by using a newer version of Netty, can you try bumping the version here to the latest 4.1.x version?

Ben Kietzman / @bkietz:
Same error is emitted with Netty 4.1.36

[asfimport]

Bryan Cutler / @BryanCutler:
Yeah, sounds like this could be related to the change in ARROW-3191 described here http://mail-archives.apache.org/mod_mbox/arrow-dev/201904.mbox/%3cCAKHW1aoU7R7wcyprd5SYmfnmC3WtC=zNnTbpB=jV3JLE=Q+TGg@mail.gmail.com%3e

@bkietz have you tried an older JDK, maybe 8? Any suggestions @siddharthteotia?

Ben Kietzman / @bkietz:
Tried again with Oracle JDK 8, got the same error:

$ apt search jdk | grep installed
jdk1.8/now 1.8.0211-1 amd64 [installed,local]
libslf4j-java/bionic,bionic,now 1.7.25-3 all [installed,auto-removable]

Bryan Cutler / @BryanCutler:
I also saw the same error with JDK 8 and 9. I got it passing for Java by adding -Dio.netty.tryReflectionSetAccessible=true to the cmd. Let me put up a PR for the fix.

Bryan Cutler / @BryanCutler:
Actually, I got it working with JDK 8 without the above conf. I think previously, I had compiled with JDK 8 and tested with JDK 9 which led to the netty error. I'll try again with just JDK 9.

setting the system properties as first line of main() succeeds for jdk12 where latest release as-of-this-comment still throws the exception cited.

@JvmStatic
fun main(vararg args: String) = runBlocking{
 System.setProperty( "io.netty.tryReflectionSetAccessible","true") 
 go(*args)
