Issue

• Currently Apache Aries Auto-Enlisting XA Wrapper feature is broken:

  • If OSGi bundle exports a service implementing javax.sql.XADataSource, then Apache Aries is supposed to pick this service up and re-export a new proxy data source service implementing javax.sql.DataSource interface.
  • This new proxy service is supposed to be used by applications and is responsible for auto-enlistment of XA connections into global JTA transaction context.
  • Upon connection closure and transaction completion, the proxy should return connection back to the pool. However, it is currently broken so connection pool is exhausted after some time.

• Example error message may be as shown below (or similar depending on connection pool implementation used):

Pool empty. Unable to fetch a connection in 30 seconds
