Looking at *StandardJtaPlatformResolver* source code, I can see that it looks first for the existence of a class com.ibm.tx.jta.TransactionManagerFactory and, if it finds it, chooses to use Liberty. At a guess, I would say this check is flawed and this class is found in Websphere 8.5.5.x not just in the Liberty profile.
