Hi everyone, I need to do some step-wise debugging on a custom RequestHandler. I'm trying to spin up a core in a Junit test, with the idea of running it inside of Eclipse for debugging. (If there's an easier way, I'd like to see a walk through!) Problem is the core fails to spin up with:
java.io.IOException: Break Iterator Rule Data Magic Number Incorrect, or unsupported data version Here's the code, just trying to load (cribbed and adapted from https://stackoverflow.com/questions/45506381/how-to-debug-solr-plugin): public class BrowseHandlerTest { private static CoreContainer container; private static SolrCore core; private static final Logger logger = Logger.getGlobal(); @BeforeClass public static void prepareClass() throws Exception { String solrHomeProp = "solr.solr.home"; System.out.println(solrHomeProp + "= " + System.getProperty(solrHomeProp)); // create the core container from the solr.solr.home system property container = new CoreContainer(); container.load(); core = container.getCore("biblio"); logger.info<http://logger.info>("Solr core loaded!"); } @AfterClass public static void cleanUpClass() { core.close(); container.shutdown(); logger.info<http://logger.info>("Solr core shut down!"); } } The test, run through ant, fails as follows: [junit] solr.solr.home= /Users/tod/src/vufind/solr/vufind [junit] SLF4J: Defaulting to no-operation (NOP) logger implementation [junit] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I don't get to dig into code very often, so my Java and IDE skills are a bit rusty. Any advice is welcome, whether how to fix or an alternate approach.
