Shutting down PersistentUnitCache thread

我可以从哪里开始寻找问题？

Answer 1

当我将 gwt 从 2.6.1 迁移到 2.8 时，我遇到了同样的问题。实际上这个错误是由 asm 依赖引起的。您的某些服务器依赖项具有对 asm 的内部依赖项。在我的情况下，它的 cglib。所以我将 cglib 更改为 cglib-nodep 并且它有效:-)

   <dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib-nodep</artifactId>
        <version>3.2.1</version>
    </dependency>
