Spi2Dav / 283 Conflict: Creation of PropertyInfoImpl fails with NPE if the returned ItemInfo points to a Node

jcr-server and jcr2spi do not deal properly with the following 283 functionality

• property and node siblings can have the same name

this results in NPE upon creation of a PropertyInfoImpl from time to time:

java.lang.NullPointerException
at org.apache.jackrabbit.spi2dav.PropertyInfoImpl.<init>(PropertyInfoImpl.java:62)
at org.apache.jackrabbit.spi2dav.RepositoryServiceImpl.getPropertyInfo(RepositoryServiceImpl.java:914)

this issue cannot be fix by checking the value of the ItemResourceConstants.JCR_TYPE.
instead a fix MUST include cover both jcr-server and jcr2spi and deal with the fact that there are
nodes/properties with the same name. consequently a different URI must be created for them
in order to have the server/client properly deal with the requests/responses.

since there are currently no plans for upgrading SPI and spi2dav in particular to jcr 283 this issue
acts as a reminder.
