[infinispan-dev] NPE on boot when using preload

To reproduce NPE start CapeDwarf twice with sample app and enabled preload for cache capedwarf/dist
<cache-container name="capedwarf" default-cache="default">
...
<distributed-cache name="dist" mode="ASYNC">
	<transaction mode="NON_XA" locking="PESSIMISTIC"/>
	<eviction strategy="LIRS" max-entries="100000"/>
	<file-store preload="true" purge="false"/>
</distributed-cache>


After some debuging, find out that
in org.infinispan.distribution.DistributionManagerImpl.getLocality
stateTransferManager.getCacheTopology() returns null
https://github.com/infinispan/infinispan/blob/5.2.0.CR1/core/src/main/java/org/infinispan/distribution/DistributionManagerImpl.java#L113

looks like onTopologyUpdate must be called first, but it is not

org.infinispan.statetransfer.StateConsumerImpl.onTopologyUpdate
https://github.com/infinispan/infinispan/blob/5.2.0.CR1/core/src/main/java/org/infinispan/statetransfer/StateConsumerImpl.java#L251
