ERROR starting neo4j service on ubuntu

I installed neo4j 2.0.0 M06 version on my Ubuntu pc. It service worked fine, and I could use the new web browser perfectly. Then, I used the sample java project (https://github.com/neo4j/neo4j/blob/2.0.0-M06/community/embedded-examples/src/main/java/org/neo4j/examples/EmbeddedNeo4jWithIndexing.java) to connect embedded way to the DB and add some nodes. (btw, I'm sure I stopped the neo4j service before launching the java application)

I changed the number of nodes added by the program to 100,000, and the application crashed on exceeding heap size (GC overhead limit).

Now, when trying to launch the neo4j I get a startup error :

I found the problem with the jar files. Unfortunately, after solving the jar files problem, I had to reinstall neo4j for the service to work again
