Denis Mekhanikov created IGNITE-9043:
----------------------------------------
Summary: Map field is registered as Object in BinaryType
Key: IGNITE-9043
URL: https://issues.apache.org/jira/browse/IGNITE-9043
Project: Ignite
Issue Type: Bug
Components: binary
Affects Versions: 2.6
Reporter: Denis Mekhanikov
Assignee: Denis Mekhanikov
Fix For: 2.7
When a binary type is registered during first insertion without use of
BinaryObject, then fields of type {{Map}} are registered as {{Object}}-s.
It leads to inconvenience in further usage of this type over {{BinaryObject}}
interface.
The following code results in an exception:
{code:java}
public static void main(String[] args) {
Ignite ignite = Ignition.start("config/ignite.xml");
IgniteCache<Integer, ExamplePojo> cache = ignite.getOrCreateCache("cache");
cache.put(1, new ExamplePojo());
BinaryObject val = cache.<Integer, BinaryObject>withKeepBinary().get(1);
Map<Integer, String> map = val.field("map");
map.put(1, "1");
BinaryObjectBuilder bldr = val.toBuilder();
bldr.setField("map", map);
bldr.build(); // Throws exception.
}
static class ExamplePojo {
Map<Integer, String> map = new HashMap<>();
}
{code}
Stacktrace:
