java - Java 11下使用CXF的类转换异常

Question

我正在将一个在 Java 8 下运行的应用程序转换为 Java 11。它使用 Apache CXF 库来处理带有附件的 Web 服务。由于企业库已从 11 JRE 中删除，因此我已将所需的库添加到类路径(SAAJ、JAXB 等)中。现在当它运行时我得到以下异常

    java.lang.ClassCastException: class com.sun.org.apache.xerces.internal.dom.ElementNSImpl cannot be cast to class javax.xml.soap.SOAPElement (com.sun.org.apache.xerces.internal.dom.ElementNSImpl is in module java.xml of loader 'bootstrap'; javax.xml.soap.SOAPElement is in unnamed module of loader 'app')

有谁知道为什么默认消息构造似乎创建了一个未实现所需 SOAPElement 接口(interface)的类的实例？

请等待 CXF 3.3.x 使用 Java 11。社区目前正在努力。您可以使用 JIRA https://issues.apache.org/jira/issues/?jql=project%20%3D%20CXF%20AND%20text%20~%20%22jdk11%22%20ORDER%20BY%20priority%20DESC%2C%20updated%20DESC跟踪状态。
