> The XAItemStateManager constructor calls the super constructor (LocalItemStateManager)  which registers the instance as a listener with the SharedItemStateManager. The construction of the instance has not yet been finished, but it is accessible from the SharedItemStateManager. This can result in strange exceptions like the following:
> java.lang.NullPointerException
>         at org.apache.jackrabbit.core.state.XAItemStateManager.stateModified(XAItemStateManager.java:580)
>         at org.apache.jackrabbit.core.state.StateChangeDispatcher.notifyStateModified(StateChangeDispatcher.java:111)
>         at org.apache.jackrabbit.core.state.SharedItemStateManager.stateModified(SharedItemStateManager.java:400)
>         at org.apache.jackrabbit.core.virtual.AbstractVISProvider.stateModified(AbstractVISProvider.java:445)
>         at org.apache.jackrabbit.core.state.ItemState.notifyStateUpdated(ItemState.java:244) 
> The NPE is caused by the commitLogs field being null (it has not yet been initialized to its final value).
