Hi Thomas.
Regarding this:

Who holds on to the PropertyImpl? Is this reference removed before or after the
save?
Im asking because while testing the code I came up with the following scenario:
JR | GC
------------------------|---------------------
add properties |
| set cut-point as part of the next scan / mark
cycle
| (won't mark recently added properties, because
they're unsaved)
save |
(evict) |
| deleteUnused()
(evict): identifiers evicted from the weak hash map
Is it possible that the identifiers get removed from the weak hash map
immediatly after the save
operation? Or the identifiers can't be removed because a hard reference to them
(ie, to the
PropertyImpl object) is kept somewhere in the Jackrabbit core? When is this
reference removed?
In testing, this is possible to do by calling the clearInUse() method you
provided. But what about a
real scenario?
I hope you can understand me. If not, I'll try to explain better.
Regards,
Esteban Franqueiro
