Hey Matteo, I think in this commit - BOOKKEEPER-964 https://github.com/apache/bookkeeper/commit/ecbb053e6e873859507e247cae727f4bc8b9f7fa , you brought Java 8 features and API but the older versions of Maven shade plugin (2.1) doesn't support Java 8 and it would cause maven build failure with the following exception. For more details check https://jira.nuxeo.com/browse/NXP-18655. In Bookkeeper-Server pom.xml you need to upgrade maven-shade-plugin version from 2.1 to 2.4.2
