[GSS](7.3.z) JBTM-3383 - Improve ARJUNA016009: Caught:: java.lang.NullPointerException log message

    XMLWordPrintable

Details

    Description

      If the global transaction identifier is null for an Xid returned by Oracle when the XAResource.recover() method is called, it causes Narayana to log a NullPointerException.

      This is caused by an XA datasource that is not compliant with JTA which requires a (non-null) byte array. 1
       
      Ideally, a warning should be logged reporting any retrievable data found in the Xid along with the datasource for which the JDBC driver's XAResource.recover(int) returned the invalid/corrupt Xid object.
