Spring-data-neo4j-Neoclipse-Lucene corrupt index Exception - exception

Question

I have configured my application using Spring-data-neo4j, where I can successfully persist, create relationships, etc.
Once I persist the data and stop my application, I then want to visualize the graph that I've created in NEOCLIPSE.
I can successfully see the graph as well in NEOCLIPSE.
The only problem I am having is.. once I close the connection in Neoclipse, and then re-run my application to listAllSavedEntities on a web page, I get this error :
`SEVERE: Servlet.service() for servlet [spring] in context with path [/sample] threw exception [Request processing failed; nested exception is java.lang.RuntimeException: org.apache.lucene.index.CorruptIndexException: unrecognized format -3 in file "_0.fnm"] with root cause

I simply closed the connection in Neoclipse and then tried to list out my persisted entities. Nothing more to that.
I am not sure what's wrong in here :( :(
Any help would be appreciated.
Thanks.

Answer 1

What neo4j kernel version does your neoclipse use and which one your application? Could it be that there is a version mismatch? Maybe neoclipse upgrades the data directories content to a newer version under the hood. That could be the cause for that unrecognized format -3 error message in your application.
