> It is possible to rollback a transaction, invoke a modification operation on
> some table, open another transaction and get 'Failed to acquire a lock due to
> a conflict' when accessing that table.
> Reproducer:
> {code:java}
> @Test
> public void testLockIsNotReleasedAfterTxRollback() {
> Ignite ignite = CLUSTER_NODES.get(0);
> IgniteSql sql = ignite.sql();
> try (Session ses = ignite.sql().createSession()) {
> ses.execute(null, "CREATE TABLE IF NOT EXISTS tst(id INTEGER
> PRIMARY KEY, val INTEGER)").affectedRows();
> }
> try (Session session = sql.createSession()) {
> Transaction tx = ignite.transactions().begin();
> assertThrows(RuntimeException.class, () -> session.execute(tx,
> "SELECT 1/0"));
> tx.rollback();
> session.execute(tx, "INSERT INTO tst VALUES (1, 1)"); // if this
> line is commented out, everything works fine.
> }
> try (Session session = sql.createSession()) {
> Transaction tx = ignite.transactions().begin(new
> TransactionOptions().readOnly(false));
> session.execute(tx, "INSERT INTO tst VALUES (1, 1)"); //IGN-TX-4
