Bringing it forwards. @oguzhanunlu please test and close if it was already fixed.

Currently, scalac 2.12.4 doesn't support jvm 9 as target. Running scalac -target under igluctl/ gives following:

scalac error: Usage: -target:<target> where <target> choices are jvm-1.5, jvm-1.6, jvm-1.7, jvm-1.8 (default: jvm-1.8)

Assembled igluctl and tested few schemas using JRE 9 on localhost and they worked fine. De-scheduling this issue for now.

It basically means that Java 9 support was added implicitly by some another ticket (most likely #287). Leaving open so far to check if anyone else will hit this issue.

I ran into this last week trying to push schemas to S3 using igluctl (version 0.3.0):

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

I could only resolve it when I downgraded to Java 8.

Thanks @carabaestlein! @oguzhanunlu can we please do one of following:

1. Figure out what brings javax/xml/bind and remove/update this dep
2. Follow Proper long-term solution instructions on link @alexanderdean provided.

Also we'll have to test all subcommands next time.

Thanks for pointing this out @carabaestlein ! Alright @chuwy , I'll resolve it when I get back.
