Kotlin isn’t a good fit for GraalVM at the moment considering the current state of Kotlin support. Not all of Kotlin’s languages features are supported by GraalVM, especially Coroutines. This is embarrassing since GraalVM is advertising Kotlin support (is premature) yet the language isn’t properly supported. When a company like Hewlett Packard Enterprise is involved you know that the GraalVM team have stuffed up big time.
