Description

BlockInfoStriped(BlockInfoStriped b) {
  this(b, b.getSchema());
  this.setBlockCollection(b.getBlockCollection());
}

protected BlockInfoContiguous(BlockInfoContiguous from) {
  this(from, from.getBlockCollection().getPreferredBlockReplication());
  this.triplets = new Object[from.triplets.length];
  this.setBlockCollection(from.getBlockCollection());
}

We should define a copy constructor in the BlockInfo, and call it from these two subclass. I also notice a NullPointerException test failure of TestBlockInfo.testCopyConstructor in latest branch which is related to this.
