Cannot build GraalVM native image for Scala 2.13

[plokhotnyuk]

It works fine for a simple hello world sample with Scala 2.11.12/2.12.10:

$ git clone -b graalvm-ce-java8-native-image --single-branch [email protected]:plokhotnyuk/jsoniter-scala.git
...
$ cd jsoniter-scala/jsoniter-scala-examples
...
$ sbt clean +assembly
...
$ /usr/lib/jvm/graalvm-ce-java8/bin/native-image --no-server --no-fallback --allow-incomplete-classpath -H:UnsafeAutomaticSubstitutionsLogLevel=3 -H:+ReportExceptionStackTraces --report-unsupported-elements-at-runtime -jar target/scala-2.12/jsoniter-scala-examples-assembly-0.1.0-SNAPSHOT.jar
...
$ time ./jsoniter-scala-examples-assembly-0.1.0-SNAPSHOT
Hello, World!

real	0m0,001s
user	0m0,001s
sys	0m0,000s

But it cannot be compiled to the native image with Scala 2.13.1:

$ /usr/lib/jvm/graalvm-ce-java8/bin/native-image --no-server --no-fallback --allow-incomplete-classpath -H:UnsafeAutomaticSubstitutionsLogLevel=3 -H:+ReportExceptionStackTraces --report-unsupported-elements-at-runtime -jar target/scala-2.13/jsoniter-scala-examples-assembly-0.1.0-SNAPSHOT.jar

do you have reason to believe this is actionable in the scala/scala repo? (regardless, the report is good to have)

[plokhotnyuk]

W/A is using of the --initialize-at-build-time option!

@olafurpg Thanks a lot for the hint, Ólafur!
