Chris Schmidt commented on JCR-888:
-----------------------------------
I've had a chance to do a bit more work on this. There is one case that I'm
not certain will keep the indexing value unfortunately. If a deployment of
JackRabbit has already created the property files and it is loaded into the IBM
1.6 JRE, the default namespace will not be found. The only way I can think of
fixing this case is if there is some mechanism to go into the filesystem and
modify the property files prior to getting loaded in the Property file.
I have a small patch that converts the empty string into a long-ish name when
persisting to a property file. That shouldn't collide with existing
URI/Prefixes, but I put the value into the restricted prefixes/uris just in
case. The conversion is done for both the index values and the prefix/uri
mapping. I've tested against a brand new deployment of JackRabbit under AIX
and an existing deployment that originally exhibited the issue prior to the
patch.
I still haven't gotten the latest version of IBMs 1.6 JDK installed on AIX to
test with. It is possible that this problem is fixed in SR4.
