io.helidon.integrations.jta.jdbc.JtaDataSource	This class is slated for removal. It makes incorrect assumptions about threading in a JTA environment. Specifically, this class' implementation incorrectly assumes that the JtaDataSource.afterCompletion(int) method will be invoked on the same thread as the governing transaction, which is not necessarily the case, especially in the case of asynchronous rollbacks.

io.helidon.integrations.jdbc.ConditionallyCloseableConnection(Connection)	This constructor continues to exist for backwards compatibility only and its use is strongly discouraged. Please use the ConditionallyCloseableConnection(Connection, boolean, boolean) constructor instead and consider supplying true for its strictClosedChecking parameter. In the future, this constructor may change, without prior notice, to cause new ConditionallyCloseableConnection instances created by it to behave as if they were created by invocations of the ConditionallyCloseableConnection(Connection, boolean, boolean) constructor instead, with true supplied for its strictClosedChecking parameter.
io.helidon.integrations.jdbc.ConditionallyCloseableConnection(Connection, boolean)	This constructor continues to exist for backwards compatibility only and its use is strongly discouraged. Please use the ConditionallyCloseableConnection(Connection, boolean, boolean) constructor instead and consider supplying true for its strictClosedChecking parameter.

io.helidon.integrations.jta.jdbc.JtaAdaptingDataSource(TransactionSupplier, TransactionSynchronizationRegistry, boolean, ExceptionConverter, XADataSource, boolean, boolean)	This constructor exists only to handle certain XA-aware connection pools that allow an end-user caller to "borrow" XAConnections and to "return" them using their close() methods, a non-standard practice which is discouraged by the documentation of PooledConnection (from which XAConnection inherits). For such connection pools, XAConnections that are "borrowed" must be returned in this manner to avoid leaks. This constructor implements this behavior. Before using it, you should make sure that the connection pool in question implementing or supplying the XADataSource has the behavior described above; normally an XAConnection should not be used directly or closed by end-user code.
