Ian Rowland updated SOLR-2130:
------------------------------
Attachment: TechSpike.zip
The attached file contains a self contained java project that will show the
problem.
Run the code in 'Main' (src/highlighting/techspike.solr.highlighting),
The first time it is run the 'index' folder does not exist and the application
completes (see output in Console window) .
The second time it runs the 'Index' folder has been created but it empty: this
causes the error to occur.
If you delete the index directory and run the app again, it works!
The application uses a RAMDirectory factory that is referenced in the
SolrConfig.xml.
The project includes the Solr libraries and they claim to be version 1.4.1!
> Empty index directory causes FileNotFoundException error when starting
> in-memory SOLR server (RAMDirectory)

> When creating an in-memory Solr Server (using RAMDIrectory) if an empty index
> directory exists when the server is created the following error occurs:
> java.lang.RuntimeException: java.io.FileNotFoundException: no segments* file
> found in org.apache.lucene.store.ramdirect...@177b093: files:
> at org.apache.solr.core.SolrCore.getSearcher(SolrCore.java:1068)
> The code expects a segment file to be present - but as it is an in-memory
> server there isn't one to find and the error occurs.
> The workaround is to ensure the directory is deleted before starting the
> server, but the creation process creates another empty index folder :(
