我有一个Java卡，并编写了一个发送APDU到Java卡的小代码。当我发送Init_Update命令时，我会收到0x6985的响应，类似于：
我有一张java卡并写了发送APDU到java卡的代码。在这里当我发送Init_Update命令时，我收到类似于0x6985的响应：
CMD -> 80 50 00 00 08 11 22 33 44 55 66 77 88
RES <- 6985
但当我使用其他工具发送此命令时，它会给出所需的结果，例如：

我的Java代码在我拥有的其他Java卡上能够正常工作。有人可以告诉我这种不同行为的原因吗？
// full java code
public static void main(String[] args) {
// TODO code application logic here
try
{
factory = TerminalFactory.getDefault();
terminals = factory.terminals().list();
terminal = terminals.get(0);
card = terminal.connect("*");
channel =card.getBasicChannel();
CommandAPDU cmdAPDU;
ResponseAPDU response;
byte[] select_isd = {(byte) 0x00,(byte) 0xA4,(byte) 0x04,(byte) 0x00,(byte) 0x08,(byte) 0xA0,(byte) 0x00,
(byte) 0x00,(byte) 0x00,(byte) 0x03,(byte) 0x00,(byte) 0x00,(byte) 0x00 };
cmdAPDU = new CommandAPDU(select_isd);
response = channel.transmit(cmdAPDU);
byte[] INIT_UPDATE = {(byte) 0x80,(byte) 0x50,(byte) 0x00,(byte) 0x00,(byte) 0x08,(byte) 0x11,(byte) 0x22,
(byte) 0x33,(byte) 0x44,(byte) 0x55,(byte) 0x66,(byte) 0x77,(byte) 0x88 };
cmdAPDU = new CommandAPDU(INIT_UPDATE);
response = channel.transmit(cmdAPDU);
}
catch( Exception ex)
{
}
}
其他工具日志看起来像：

但是当我运行我的Java代码时，INIT_UPDATE命令返回6985。
如果需要其他信息，请告诉我。
==新添加的内容=== 我尝试在JCOP shell中运行我的脚本，我的脚本类似于：
/mode trace=on
/terminal
/atr
/send 80CAA08D05
/send 802E000014B555C94B0B2368B4840201808502032288020060
/send 80D8000000
/atr
/send 80500000081122334455667788
我已经得到了所需的结果。我试着在Java中实现它，我的新Java代码看起来像：
