-------------------------------------
My code is the following:
{code}
File rootDir = createRootDir(); //Creating root directory of the index
EmbeddedCacheManager cacheManager = null;
createIndex(rootDir, indexName, elementCount, true); //Manually writes some data to the
index with number of elementCount to index with name indexName - as is done in
org.infinispan.lucene.cacheloader.IndexCacheLoaderTest
ConfigurationBuilder builder = new ConfigurationBuilder();
builder
.loaders()
.addLoader()
.cacheLoader( new LuceneCacheLoader() )
.addProperty(LuceneCacheLoaderConfig.LOCATION_OPTION, rootDir.getAbsolutePath())
.addProperty(LuceneCacheLoaderConfig.AUTO_CHUNK_SIZE_OPTION, "1024");
EmbeddedCacheManager cacheManager = TestCacheManagerFactory.createCacheManager(builder);
LuceneCacheLoader cacheLoader = (LuceneCacheLoader)
TestingUtil.extractComponent(cacheManager.getCache(),
CacheLoaderManager.class).getCacheLoader();
Set keyList = cacheLoader.loadAllKeys(null); // <<<----- This is the line which
throws the NullPointerException.
{code}
According to JavaDoc, if null is passed as a parameter to loadAllKeys() method, then it
should load all keys without exclusions, but instead it throws NullPointerException.
