jar --describe-module shows lower-case service impl name

[Christian Stein]

Hi,

just saw running on JDK 11-ea+13 that:

  jar --describe-module --file <archive> [1]

shows:

  provides org.junit.platform.engine.TestEngine with ice.cream.machine [2]

The FQCN service implementation name is: ice.cream.Machine

Is this a known and perhaps intended behavior?

Cheers,
Christian
