Attaching ignite config. A failed code is a simple execution of hibernate
query. Here is bigger stacktrace:
Caused by: java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast
to [Ljava.io.Serializable;

For now I created 'dirty' workaround to continue with my testing:
org.apache.ignite.cache.hibernate.HibernateQueryResultsRegion#get
@Override
public Object get(SharedSessionContractImplementor
sharedSessionContractImplementor, Object key) throws CacheException {
Object result = super.get(sharedSessionContractImplementor, key);
if (result instanceof List) {
List list = (List) result;
if (list.size() > 1) {
for (int i = 1; i < list.size(); i++) {//first element in
list is id, skip it
Object row = list.get(i);
if (row != null && row.getClass().isArray())
{//convert Object[] to Serializable[]
Object[] rowArr = (Object[]) row;
list.set(i, Arrays.copyOf(rowArr, rowArr.length,
Serializable[].class));
}
}
}
}
return result;
}
