[infinispan-issues] [JBoss JIRA] (ISPN-4583) Distributed iterator throws ClassCastException when LevelDB cache store contains passivated entries

Distributed iterator throws ClassCastException when LevelDB cache store contains passivated entries --------------------------------------------------------------------------------------------------- Key: ISPN-4583 URL: https://issues.jboss.org/browse/ISPN-4583 Project: Infinispan Issue Type: Bug Security Level: Public(Everyone can see) Components: Core Affects Versions: 7.0.0.Alpha5 Reporter: Alan Field Assignee: William Burns Attachments: repl-udp-no-tx-leveldb-jni.xml This code will iterate over all of the entries in a cache to get the total size: {code:java} public int getTotalSize() { log.info(getClass().getName() + ".getTotalSize() for cache " + cache.getName()); int totalSize = 0; EntryIterable entryIterator = null; try { entryIterator = cache.filterEntries(new AllEntriesFilter()); CloseableIterable ci = entryIterator.converter(new AllEntriesConverter()); Iterator iter = ci.iterator(); while (iter.hasNext()) { iter.next(); totalSize++; } return totalSize; } finally { if (entryIterator != null) { try { entryIterator.close(); } catch (Exception e) { log.error("Failed to close EntryIterable", e); } } } } {code} I wanted to verify that this code would also work when I was using passivation and a cachestore. The repl-udp-no-tx-leveldb-jni.xml file defines the configuration that I am using. I run a test that puts random data into the cache then checks the size of the cache, but I am getting a bunch of ClassCastException exceptions during the iteration: {noformat} java.lang.ClassCastException: java.lang.String cannot be cast to org.infinispan.container.entries.InternalCacheEntry at org.infinispan.iteration.impl.LocalEntryRetriever$MapAction.apply(LocalEntryRetriever.java:251) at org.infinispan.iteration.impl.LocalEntryRetriever$KeyValueActionForCacheLoaderTask.processEntry(LocalEntryRetriever.java:154) at org.infinispan.persistence.leveldb.LevelDBStore$1.call(LevelDBStore.java:297) at org.infinispan.persistence.leveldb.LevelDBStore$1.call(LevelDBStore.java:285) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at org.infinispan.util.concurrent.WithinThreadExecutor.execute(WithinThreadExecutor.java:22) at java.util.concurrent.ExecutorCompletionService.submit(ExecutorCompletionService.java:181) at org.infinispan.executors.ExecutorAllCompletionService.submit(ExecutorAllCompletionService.java:31) at org.infinispan.persistence.leveldb.LevelDBStore.submitProcessTask(LevelDBStore.java:285) at org.infinispan.persistence.leveldb.LevelDBStore.process(LevelDBStore.java:260) at org.infinispan.persistence.manager.PersistenceManagerImpl.processOnAllStores(PersistenceManagerImpl.java:438) at org.infinispan.persistence.manager.PersistenceManagerImpl.processOnAllStores(PersistenceManagerImpl.java:420) at org.infinispan.iteration.impl.LocalEntryRetriever$1.run(LocalEntryRetriever.java:217) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) {noformat}
