APAR status

  • Closed as program error.

Error description

  • When performing multi-threaded deployments, it is possible for
    two threads to perform a first lookup of a data source, which
    causes the initialization logic of a single ConnectionFactory to
    run twice.
    
    This problem manifests as an IllegalStateException when a "set
    once" property is set twice -- once on each thread.
    
    Caused by: java.lang.IllegalStateException:
    J2CGlobalConfigProperties:
    internal error.  Set once property already set.
