java.lang.LinkageError : loader constraint violation in interface itable initialization 错误

Question

当我执行我的代码时，出现以下错误。这是我从 JDK 1.6 升级到 1.8 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

在测试用例中使用注解@PowerMockIgnore("javax.security.*") 解决了我的测试用例失败问题。
