We do have utilities to work with JCR such as NodeUtil or PropertyUtil.
These are quite hard to use inside of Streams/Optionals because of checked exceptions they throw.
The usual solution so far is extraction the calls to a method:

Optional.of(Node).map(getName());

String getName(Node node) {
  try {
     return node.getName();
  } catch (RE e) {
    throw new RuntimeRepositoryException(e);
  }
}

As result, such methods are duplicated all over the place.
The goal of this ticket would be introduce a utitility which would do the exception handling itself.
