------------------------------------------
Summary: Java thin client: Wrong typeId generation for system types
Key: IGNITE-12624
URL: https://issues.apache.org/jira/browse/IGNITE-12624
Project: Ignite
Issue Type: Bug
Components: binary, thin client
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
Thin client generates wrong {{typeId}} for system types. This is caused by
{{ClientMarshallerContext}} implementation, which always returns {{false}} for
{{isSystemType}} method. These leads to {{typeId}} duplication for the same
class and assertions when trying to get object by thick client. Reproducer:
{code:java}
thinClient.cache(DEFAULT_CACHE_NAME).put(1, CacheAtomicityMode.ATOMIC);
thickClient.cache(DEFAULT_CACHE_NAME).get(1);
{code}
Assertion:
{noformat}
java.lang.AssertionError: Duplicate typeId [typeId=1984564222, cls=class
org.apache.ignite.cache.CacheAtomicityMode, desc=BinaryClassDescriptor
[cls=class org.apache.ignite.cache.CacheAtomicityMode, serializer=null,
initialSerializer=null, mapper=BinaryInternalMapper

If we perform "put" operation with value of the same type from thick client
before "get" operation, there is no assertion anymore, but {{typeId}} is still
duplicated. And there is another issue: different marshallers can be used to
marshal the same class for thin and thick clients, wrong class descriptor is
returned for class name and there is assertion again. Reproducer:
{code:java}
thickClient.cache(DEFAULT_CACHE_NAME).put(3, Collections.emptyList());
thinClient.cache(DEFAULT_CACHE_NAME).put(2, Collections.emptyList());
thickClient.cache(DEFAULT_CACHE_NAME).get(2);
{code}
Assertion:
{noformat}
java.lang.AssertionError: OptimizedMarshaller should not be used here:
