ClassCastException: Iterator returning instance of MarshalledValue instead of real object

[lucianom86]

Hi all,

We have a few applications using Infinispan 7.1.1 and when we iterate over the values of the cache, we sometimes are getting a ClassCastException:

org.infinispan.marshall.core.MarshalledValue cannot be cast to org.apache.solr.common.SolrInputDocument (this is the type of object we're storing as the value of the cache)

This happens in just a few occasions, most of the times everything works as expected. I added a log message to print out the key and value of the entry before getting the exception and here what I got in case of error:

2015-07-22 16:49:37,009 INFO Analyzing the key 1437580176892 and value MarshalledValue{serialized=[B0x0301fe0409000000..[3136]}@3057898

When we get no error, the message is:

2015-07-22 16:49:43,200 INFO Analyzing the key 1437580163898 and value SolrInputDocument(fields: ..)

This cache is replicated sync among 2 nodes, but the process of iterating over the cache just happens in a single node.

We're using the storeAsBinary() as follows:

configurationBuilder.storeAsBinary().enable().storeKeysAsBinary(false).storeValuesAsBinary(true);

Any idea of what may be causing this issue?

Thanks in advance,

Luciano
