我在java程序中遇到这个异常。任何人都有这个想法吗？

为什么会出现此异常。你们有什么想法解决它吗？
答案 0 :(得分：2)
来自org.jboss.remoting.transport.socket.MicroSocketClientInvoker Javadoc：
boolean java.io.ObjectInputStream.BlockDataInputStream.setBlockDataMode（boolean newmode）抛出IOException
将块数据模式设置为给定模式（true == on，false == off）和 返回先前的模式值。如果新模式与 旧模式，不采取任何行动。如果阻止，则抛出IllegalStateException 当未消耗的块数据时，数据模式从开启切换到关闭 仍然存在于流中。
但是在你的堆栈跟踪中，问题的起源是{{1}}来处理某些对象的反序列化。
所以，你可以想象只用堆栈跟踪很难猜出这个错误的原因。 运气不错，你可以得到准确的答案。 但如果不是这样的话，我建议你做一些跟踪：
