Magic! That helps a lot. Thank you, Andrey. The warning message makes me 
a bit nervous, though.

$ ./opt/jre-10/bin/java -XX:-AssumeMP -jar lib/hellojdk.jar
OpenJDK Server VM warning: Option AssumeMP was deprecated in version 
10.0 and will likely be removed in a future release.

$ ./opt/jre-11/bin/java -XX:-AssumeMP -jar lib/hellojdk.jar

10.0 and will likely be removed in a future release.

Should I open a bug report?

Thank you,
