             Summary: "storeAsBinary" option causes ClassCastException when putting an element into FineGrainedAtomicMap
                 Key: ISPN-3970
                 URL: https://issues.jboss.org/browse/ISPN-3970
             Project: Infinispan
          Issue Type: Bug
    Affects Versions: 6.0.1.Final
            Reporter: Gunnar Morling
            Assignee: Mircea Markus


When enabling the "storeAsBinary" mode, I'm getting a {{ClassCastException}} when putting an element into a {{FineGrainedAtomicMap<String, Object>}}:

{code}
Configuration configuration = new ConfigurationBuilder()
	.storeAsBinary()
		.enable()
	.transaction()
		.transactionMode(TransactionMode.TRANSACTIONAL )
		.transactionManagerLookup(new JBossStandaloneJTAManagerLookup() )
	.build();

EmbeddedCacheManager manager = new DefaultCacheManager();
manager.defineConfiguration( "testCache", configuration );

Cache<String, Object> cache = manager.getCache( "testCache", true );
String rowKey = "Some Key";

FineGrainedAtomicMap<String, Object> map = AtomicMapLookup.getFineGrainedAtomicMap( cache, rowKey, true );

// Causes ClassCastException
map.put( "the key", "the value" );
{code}

The strack trace is:

The issue does not occur when using a custom key type instead of {{String}}.
