When the network consists of a single peer a NullPointerException is caused by inserting a value into the DHT.

hi,I have met this problems.when I try to debug it,I find the codes between the version 1.04 and the version 1.05 are different!
version 1.0.4 Nodeimpl.java (246-251)
if ((this.references.getPredecessor() != null)
&& !toInsert.getId().isInInterval(
this.references.getPredecessor().nodeID, this.nodeID)) {
this.references.getPredecessor().insertEntry(toInsert);
return;
}
version 1.0.5 Nodeimpl.java (246-251)
if ((this.references.getPredecessor() == null)
|| !toInsert.getId().isInInterval(
this.references.getPredecessor().getNodeID(), this.nodeID)) {
this.references.getPredecessor().insertEntry(toInsert);
return;
}
so I try to use these codes in the version 1.0.4 to replace that codes in the version 1.0.5,then complie again,then success!
