应该是jdk的问题，我也遇到这个情况了，后来把jdk降级到8就可以了。

Seems to be an issue of kryo-serializers with openjdk 10.

Fixed with https://github.com/magro/kryo-serializers/pull/106 (released with kryo-serializers 0.45). Please override the version of kryo-serializers in your pom.xml by adding

<dependency>

  <artifactId>kryo-serializers</artifactId>
  <version>0.45</version>
