> When I try to fill distributed cache with indexing enabled concurrently from multiple threads, I get 
> {code}
> org.hibernate.search.exception.SearchException: HSEARCH000083: Unable to serialize List<LuceneWork>
>         at org.hibernate.search.indexes.serialization.impl.LuceneWorkSerializerImpl.toSerializedModel(LuceneWorkSerializerImpl.java:92)
>         ...
> Caused by: java.lang.ArrayIndexOutOfBoundsException: 6
>         at java.util.ArrayList.add(ArrayList.java:412)
>         at org.hibernate.search.indexes.serialization.avro.impl.AvroSerializer.addFieldWithStringData(AvroSerializer.java:258)
>         at org.hibernate.search.indexes.serialization.impl.LuceneWorkSerializerImpl.buildDocument(LuceneWorkSerializerImpl.java:174)
>         at org.hibernate.search.indexes.serialization.impl.LuceneWorkSerializerImpl.toSerializedModel(LuceneWorkSerializerImpl.java:80)
> {code}
> There are multiple different exceptions as cause, but the reason is one: {{AvroSerializer}} is not thead-safe. {{AvroSerializerProvider}} returns always the same instance, and so does {{InfinispanIndexManager}} (or rather {{DirectoryBasedIndexManager}}) return the same instance of {{LuceneWorkSerializerImpl}} wrapping the {{AvroSerializerProvider}}.
> This results in failed writes, corrupted data and another fun.
