SessionChangeManager should restore attribute lock after session failover
-------------------------------------------------------------------------
Key: TRINIDAD-1939
URL: https://issues.apache.org/jira/browse/TRINIDAD-1939
Project: MyFaces Trinidad
Issue Type: Bug
Components: Components
Affects Versions: 1.2.12-core
Reporter: Yuan Gao
The issue is in SessionChangeManager, we have an attribute lock, as this:
private transient final Object _attrRebuildLock = new Object();
And we synchronize on this object when we want to modify the changes arrays.
When failover happens, this field becomes null. And future synchronization will
fail since it's null. The fix is to implement the readObject() method, and
re-initialize the _attrRebuildLock field to be new Object();
private void readObject(java.io.ObjectInputStream in)
throws IOException, ClassNotFoundException
{
in.defaultReadObject();
_attrRebuildLock = new Object();
}
