unmanaged-jpa demo doesn't work

[PavelTurk]

I used karaf 4.0.5. I completed all steps that are provided in instructions. This is my bundle list:

karaf@root()> bundle:list
START LEVEL 100 , List Threshold: 50

ID | State | Lvl | Version | Name

52 | Active | 80 | 3.18.1.GA | Javassist
53 | Active | 80 | 1.1.1 | geronimo-jta_1.1_spec
54 | Active | 80 | 2.7.7.5 | Apache ServiceMix :: Bundles :: antlr
55 | Active | 80 | 1.6.1.5 | Apache ServiceMix :: Bundles :: dom4j
56 | Active | 80 | 5.0.0.Final | hibernate-commons-annotations
57 | Active | 80 | 5.0.0.Final | hibernate-core

63 | Active | 80 | 1.3.170 | H2 Database Engine
64 | Active | 80 | 1.0.0 | unmanaged-jpa

This is the result:
karaf@root()> dp:addJPA Nick
Error executing command: Unable to locate persistence units

This is from log:
