Avoid use of JDK8Module

[mebigfatguy]

My understanding (please correct me) is that jackson-datatype-jdk8 is no longer necessary as it's been merged to other jars. However, when using graphql, i still see a

mapper.registerModule(new Jdk8Module());

at

java.lang.ClassNotFoundException: com.fasterxml.jackson.datatype.jdk8.Jdk8Module
Caused by:java.lang.NoClassDefFoundError: com/fasterxml/jackson/datatype/jdk8/Jdk8Module at graphql.kickstart.execution.config.ConfiguringObjectMapperProvider.<init>(ConfiguringObjectMapperProvider.java:17)

Is there a way to tell graphql, not to register that module, or am i confused?

@mebigfatguy Hi, the graphql-java library now supports jdk-11 or above so the Jdk8Module for Jackson is no longer needed! I will open a PR asap to fix this!

Thanks for your feedback!
