Aleksey Plekhanov commented on IGNITE-13401:
--------------------------------------------
[~marcuslo], thanks for the report!
The root cause of the problem: first byte of your serialized configuration is
103 (length of configuration % 256), it's wrongly treated by thin client
marshaller as start of the new object, but actually it's just count of bytes to
read. Marshaller tries to deserialize this object and fails.
Workaround: change something in your cache configuration to change it
serialized length (for example change name of some field, change cache name,
add some dummy field etc.)

> Key: IGNITE-13401
> URL: https://issues.apache.org/jira/browse/IGNITE-13401
> Project: Ignite
> Issue Type: Bug
> Components: thin client
> Affects Versions: 2.8.1
> Reporter: Marcus Lo
> Assignee: Aleksey Plekhanov
> Priority: Major
>
> We encounter BinaryObjectException: Unsupported protocol version: 8 in one of
> our tables in Ignite when querying cache configuration via Java thin client.
> To reproduce:
> # Setup Ignite with persistence disabled (single node)
> # Create the follow table:
> {code:java}
> CREATE TABLE IF NOT EXISTS LEOD_CONTEXT_STATUS
> (
> flashNode VARCHAR NOT NULL,
> legalEntity VARCHAR NOT NULL,
> account VARCHAR NOT NULL,
> userId VARCHAR NOT NULL,
> eqtgContext VARCHAR NOT NULL,
> submissionDate INT NOT NULL,
> action VARCHAR NOT NULL,
> actionTime TIME NOT NULL,
> runNumber INT NOT NULL,
> segment VARCHAR NOT NULL,
> geography VARCHAR NOT NULL,
> priceVersion VARCHAR NOT NULL,
> status VARCHAR NOT NULL,
> errorCount INT NOT NULL,
> comments VARCHAR,
> equityDeltaLowerBound DOUBLE,
> equityDeltaUpperBound DOUBLE,
> equityDeltaUtil DOUBLE,
> equityVegaLowerBound DOUBLE,
> equityVegaUpperBound DOUBLE,
> equityVegaUtil DOUBLE,
> lastUpdateTime TIMESTAMP NOT NULL,
> PRIMARY KEY (flashNode, legalEntity, account, submissionDate)
> )
> WITH "template=REPLICATED, cache_name=LeodContextStatusCache";{code}
> # Run the following test (in Kotlin):
> {code:java}
> @Test
> fun `moo`() {
> val config = ClientConfiguration()
> .setAddresses("localhost:10800")
> val ignite = Ignition.startClient(config)
> ignite.cache<Any, Any>("LeodContextStatusCache")
> .configuration
> }
> {code}
> # It fails in the following exception:
> {code:java}
