      The test case consisting of a servlet and two stateless session beans.

      The servlet and SLSB A are deployed on node A and SLSB B is deployed on node B.

      The servlet calls SLSB A on node A. The bean then retrieves XA data source from JNDI, creates JDBC connection and inserts a row into a table in the database (Postgres).
      Next it retrieves JmsXa connection factory from JNDI, creates connection and sends a message to a queue.
      After that it calls SLSB B on node B that retrieves XA data source from JNDI, creates JDBC connection and inserts a row into a table in the database.

      At the end it should produce two rows in the database table and a message on the queue.

      Node A has a simple byteman rule that kills node A JVM at the end of BasicAction.prepare() method. After JVM on node A dies, the JVM on node B gets "kill -9".

      The above test case produces two different results that depend on the order in which JBoss nodes are restarted.

      If node is restarted A first followed by node B the outcome is consistent result i.e. two rows can be seen in the database.

      If the node B is restarted first followed by node A the outcome is inconsistent i.e. only one row in the table; row inserted by SLSB A on node A.

      Both beans use the default attributes for transaction support and both nodes have been configured to use JTS transactions.

      During recovery node B reports the following error:
