"SQLServerException: The function START: failed. No transaction cookie was returned." in JBoss EAP

Issue

• Defined two XA datasource pools referencing a single (the same) database server endpoint (same URL/host/database and user/password)
• XA has been enabled in the database server

• When both XA datasource pools are used in a single transaction, the SQL Server driver raises

  ... javax.transaction.xa.XAException: com.microsoft.sqlserver.jdbc.SQLServerException: The function START: failed. No transaction cookie was returned.
