Commit https://github.com/jbosstm/jboss-transaction-spi/commit/ed9db08f602e82d498df332382566bd816645556 in Transactions SPI 7.1.0.SP1 which is a backport of https://github.com/jbosstm/jboss-transaction-spi/commit/b7fe456fb890ccbab651b8e998ff9411803310bc available in Transactions SPI 7.3.3.Final
needs to find its way to EAP 7.0.x so that the "fix all later EAP versions" requirement is fulfilled for EAP 6.4
