Question

当我执行我的代码时，我收到以下错误。这是在我从JDK 1.6升级到1.8

之后发生的

java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "javax.security.auth.kerberos.JavaxSecurityAuthKerberosAccessImpl.keyTabTakeSnapshot(Ljavax/security/auth/kerberos/KeyTab;)Lsun/security/krb5/internal/ktab/KeyTab;" the class loader (instance of org/powermock/core/classloader/MockClassLoader) of the current class, javax/security/auth/kerberos/JavaxSecurityAuthKerberosAccessImpl, and the class loader (instance of <bootloader>) for interface sun/security/krb5/JavaxSecurityAuthKerberosAccess have different Class objects for the type javax/security/auth/kerberos/KeyTab used in the signature

Answer 1

在测试用例中使用注释@PowerMockIgnore（＆＃34; javax.security。*＆＃34;）解决了我的测试用例的失败。

Answer 2

Java 8在允许的字节代码方面更为严格。一些模拟工具使用了一些不寻常的字节码检测。

最有可能的解决方法是升级你的powermock，因为它很可能已被修复以使用Java 8。
