Symptoms

From WebLogic (WLS) 12.1.2, weblogic.datasource.endLocalTxOnNonXAConWithCommit is added as system property.
If application does not complete (commit or rollback) the local transaction before closing the non-XA connection, it expects that the connection will be committed when the property is true (default value is true).

Reference:
Oracle® Fusion Middleware Administering JDBC Data Sources for Oracle WebLogic Server
Chapter 9 - JDBC Data Source Transaction Options
Local Transaction Completion when Closing a Connection

However, if a non-XA connection has been used in global transaction once, the connection is not committed after closing connection without commit/rollback.

Therefore, if the application does not call commit or rollback explicitly for the connection, it remains non-resolved transaction or the connection will be committed/rolled back on the unexpected timing.

In summary, this issue occurs under the following conditions:

- weblogic.datasource.endLocalTxOnNonXAConWithCommit is true (default is true).
- setAutoCommit is false.
- Application does not complete (commit/rollback) the local transaction before closing the non-XA connection.
- The Non-XA connection has been used in global transaction before used in local transaction. (It means that it has been used as JTSConnection).
