As Ilya said, the underlying error is:

As a guess — this is not tested — you’d need something like:
IgniteCache<String, Object> cache = ignite.cache(cacheName);
cache.loadCache((k,v) -> {
String firstName;
if (v instanceof BinaryObject) {
BinaryObject vb = (BinaryObject)v;
firstName = v.field(“firstName”);
}
else {
firstName = v.getFirstName();
}
return ("XXXX".equalsIgnoreCase(firstName));
});
