>          Issue Type: Bug
>          Components: Caching , Session Management
>    Affects Versions: 1.1.0, Incubation
>         Environment: Linux 2.6.34 x86_64
> java version "1.5.0_12"

> org.apache.shiro.session.mgt.SimpleSession fails deserialization with the following error:
> 	at java.io.ObjectInputStream$BlockDataInputStream.readByte(ObjectInputStream.java:2666)
> 	at java.io.ObjectInputStream$BlockDataInputStream.readUTFChar(ObjectInputStream.java:3058)
> 	at java.io.ObjectInputStream$BlockDataInputStream.readUTFBody(ObjectInputStream.java:2955)
> 	at java.io.ObjectInputStream$BlockDataInputStream.readUTF(ObjectInputStream.java:2764)
> 	at java.io.ObjectInputStream.readUTF(ObjectInputStream.java:1032)
> 	at org.apache.shiro.session.mgt.SimpleSession.readObject(SimpleSession.java:481)
> There is a problem with the way the 'expired' flag is managed. In writeObject the 'expired' flag is written if it's set:
> if (expired) {
>     out.writeBoolean(expired);
> }
> But, in getAlteredFieldsBitMask, the bit in the bit mask is only set when the 'exprired' flag is not set:
> bitMask = !expired ? bitMask | EXPIRED_BIT_MASK : bitMask;
> A short test:
> SimpleSession session = new SimpleSession("localhost");
> //  This doesn't work either
> // session.setExpired(true);
> ByteArrayOutputStream serialized = new ByteArrayOutputStream();
> ObjectOutputStream serializer = new ObjectOutputStream(serialized);
> serializer.writeObject(session);
> serializer.close();
> new ObjectInputStream(new ByteArrayInputStream(serialized.toByteArray())).readObject();
