【问题描述】：
我正在尝试将我的项目更新到 Java 11 - OpenJDK_11.0.2（目前在 Java 8 上）。我正在使用 runjettyrun 和 Jetty 版本 9.4.8.v20171121。
我可以在 Java 8 上毫无问题地运行该项目，但如果我切换到 Java 11，我将收到以下错误消息：
MultiException[java.lang.RuntimeException: Error scanning file /Users/.../target/classes/.../entities/InventoryItemWithEnum.class, java.lang.RuntimeException: Error scanning file /Users/.../target/classes/.../entities/NeededItem.class, java.lang.RuntimeException: Error scanning file /Users/.../target/classes/.../entities/InventorySnapshot.class, java.lang.RuntimeException: Error scanning file /Users/.../target/classes/.../entities/InventoryItemAmount.class, java.lang.RuntimeException: Error scanning file /Users/.../target/classes/.../entities/TransferOrders.class, java.lang.RuntimeException: Error scanning file /Users/.../target/classes/.../entities/ItemSets.class, java.lang.RuntimeException: Error scanning file /Users/.../target/classes/.../entities/SearchSerialnumberView.class]

【问题讨论】：
-
根本原因是旧版本的
asm能够扫描较新的类 -
它不仅仅是
asm，它也是较旧的 Jetty 实现，它不包含要扫描的 JAR 中的更新排除内容列表（Java 9 / JEP-238 带来的内容） )。
