SPI requirement for NoteIds of referenceable Nodes

[Julian Reschke]

Hi,

it seems that currently JCR2SPI assumes that the NoteIds returned for 
referenceable nodes actually do contain the UUID of that Node -- if the 
SPI implementation returns an absolute path based NodeID instead, 
JCR2SPI's Node.getUUID() implementation fails.

Proposals:

Either

1) Decide that this is how things are supposed to work, and just 
document it. Drawback: there may be repositories that have referencable 
nodes but path-based lookup still is more efficient (however, in that 
case the implementation could build a custom NodeId that contains both).

or

2) Change JCR2SPI to that it does not make that assumption, but instead 
retrieves the value of the jcr:uuid property.

Additional thought: before making a decision on this we may want to look 
at what new requirements JSR283 brings to the table.

BR, Julian
