Description

We encounter BinaryObjectException: Unsupported protocol version: 8 in one of our tables in Ignite when querying cache configuration via Java thin client. To reproduce:

1. Setup Ignite with persistence disabled (single node)
2. Create the follow table:

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";

1. Run the following test (in Kotlin):

@Test
fun `moo`() {
    val config = ClientConfiguration()
        .setAddresses("localhost:10800")

    val ignite = Ignition.startClient(config)

    ignite.cache<Any, Any>("LeodContextStatusCache")
        .configuration
}

1. It fails in the following exception:

class org.apache.ignite.binary.BinaryObjectException: Unsupported protocol version: 8
 at org.apache.ignite.internal.binary.BinaryUtils.checkProtocolVersion(BinaryUtils.java:796) at org.apache.ignite.internal.binary.BinaryReaderExImpl.<init>(BinaryReaderExImpl.java:221) at org.apache.ignite.internal.binary.BinaryReaderExImpl.<init>(BinaryReaderExImpl.java:186) at org.apache.ignite.internal.binary.BinaryReaderExImpl.<init>(BinaryReaderExImpl.java:165) at org.apache.ignite.internal.client.thin.ClientUtils.cacheConfiguration(ClientUtils.java:381) at org.apache.ignite.internal.client.thin.TcpClientCache.lambda$getConfiguration$2(TcpClientCache.java:160) at org.apache.ignite.internal.client.thin.TcpClientChannel.receive(TcpClientChannel.java:247) at org.apache.ignite.internal.client.thin.TcpClientChannel.service(TcpClientChannel.java:171) at org.apache.ignite.internal.client.thin.ReliableChannel.service(ReliableChannel.java:180) at org.apache.ignite.internal.client.thin.TcpClientCache.getConfiguration(TcpClientCache.java:155)

I notice that if any one of the columns is removed, the issue disappears.
