Jonathan Halliday commented on JBTM-505:

Both jca.SubordinateTransaction versions should implement a common interface, SubordinateTransaction, with the methods needed to drive 2PC phases individually.  The TxImporter classes should make methods non-static and the classes each implement the new TransactionImporter interface. Add SubordinationManager factory class to return appropriate instances of TransactionImporter and XATerminator based on the configured TransactionManager type. Ensure the SubordinateTransaction unit tests are made generic and that they run in both JTA and JTAX modes.

> The JTA and JTAX both have similar support for JCA tx inflow, using TxImporter, XATerminator and TransactionImple classes. However, these have little in common beyond the name, making it difficult for user code to switch between running the JTA or JTAX versions. Refactor to introduce common interfaces & such, so that client code can exploit polymorphism rather than using way too many if/else constructs.
