Question

当我尝试模仿JTextField时，我收到此错误。

java.lang.LinkageError: loader constraint violation in interface itable
    initialization: when resolving method
    "javax.swing.text.JTextComponent$1.dropLocationForPoint(
    Ljavax/swing/text/JTextComponent;Ljava/awt/Point;)Ljavax/
    swing/TransferHandler$DropLocation;" the class loader (instance of
    org/powermock/core/classloader/MockClassLoader) of the current
    class, javax/swing/text/JTextComponent$1, and the class loader
    (instance of <bootloader>) for interface
    sun/swing/SwingAccessor$JTextComponentAccessor have different Class
    objects for the type mponent$1.dropLocationForPoint(Ljavax/swing/text/
    JTextComponent;Ljava/awt/Point;)Ljavax/swing/TransferHandler$
    DropLocation; used in the signature
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:191)
at javassist.runtime.Desc.getClassObject(Desc.java:43)

我试着用这个：

@PowerMockIgnore( {"javax.management.*","javax.security.*","javax.ws.*"})

没有任何效果。

根据cited issue的情况，我提供了一种解决方法：问题出现在javax.swing.text.JTextComponent的静态初始值设定项中，因此我们可以使用{{ 来抑制该代码1}}。

这是一个工作测试用例（使用Powermock 1.6.4）：

@SuppressStaticInitializationFor("javax.swing.text.JTextComponent")

java.lang.LinkageError：接口itable初始化中的加载器约束违规：
