我正在学习Broadleaf Getting Started教程，但遇到了一些奇怪的错误（NullPointer和Bean未找到异常）。
TL; DR：Broadleaf 6.0.x可与Java 8-10（构建，运行）一起使用。导入Maven依赖项时，还需要将其与目标一起导入JDK 8（提示：多版本jar）。它也仅适用于HotSpot VM（不适用于OpenJ9）。
官方声明（来自Broadleaf Gitter）：
受支持的Java版本与以下版本紧密相关：弹簧。 Broadleaf版本6.0.x使用的是Spring Framework5.0.8.RELEASE支持JDK 8-10（我们继续推荐Java 8）。直到Spring Framework 5.1才支持JDK 11，我们将在6.1.0-GA版本中进行升级。我没有发布日期6.1.0-GA尚未发布，但将在年底之前发布。
复制：
git clone
mvn clean install
cd site
mvn spring-boot:run
版本：标签/broadleaf-6.0.6-GA和develop-6.0.x。
