.lang.IllegalStateException: unread block data
Hello,
I'm having a very strange problem with little program I'm developing.
-- CODE --
ObjectInputStream is = new ObjectInputStream(new FileInputStream(file));
memory_test = (MemoryTestData)is.readObject();
is.close();
-
At the runtime I'm getting a 'java.lang.IllegalStateException: unread block data' at the readObject(), and the strange thing is that this only happens when I try to open the same one file (it only happens with one of my files) two consecutive times. If I open one other file in between I don't get any error, neither when I open any other file two or more consecutive times.... It only happens with a file which has 34.4Mb, all my other files are considerably smaller as they were only for testing purpose.
Does anyone have an idea of what might be happening?
Here's the Stack Trace (Long):
