3.6.2.Final, 4.0.0.Beta6
GraalVM has the capability of generating a SubstrateVM native image, which then doesn't require any JDK to run. This is very useful for minimizing app footprint and speeding up startup, among other things.
When I attempt to generate a native image of an application which bundles RESTEasy, I get an exception coming from the fact that
org.jboss.resteasy.plugins.providers.DocumentProvider
doesn't have a no-arg constructor while still being available through Java's ServiceLoader SPI.
The following is the output of the `native-image` tool, adjusted to remove the specifics of my application.
