程序使用ObjectOutputStream（new FileOutputStream（fileName,true））向文件尾写入多个对象，多次运行，最后进行读取的时候抛出StreamCorruptedException

public ObjectOutputStream(OutputStream out) throws IOException {
verifySubclass();
bout = new BlockDataOutputStream(out);
handles = new HandleTable(10, (float) 3.00);
subs = new ReplaceTable(10, (float) 3.00);
enableOverride = false;
writeStreamHeader();                     //向文件写入header信息
bout.setBlockDataMode(true);
if (extendedDebugInfo) {
debugInfoStack = new DebugTraceInfoStack();
} else {
debugInfoStack = null;
}
}

class MyObjectOutputStream extends ObjectOutputStream { 

public MyObjectOutputStream() throws IOException { 
super(); 
}
public MyObjectOutputStream(OutputStream out) throws IOException {
super(out);
} 
@Override

protected void writeStreamHeader() throws IOException { 　　　　//重写该方法
return;
}
}

if (file.length() < 1) {  　　　　//若文件不存在或文件为空使用ObjectOutputStream写入对象
oos = new ObjectOutputStream(new FileOutputStream(file, true));
} else {　　　　　　　　　　//文件不为空则用MyObjectOutputStream写入对象
oos = new MyObjectOutputStream(new FileOutputStream(file, true));
}
