Thanks Sanne and Gail. While that certainly seems like an issue when creating disassembledStateText for a byte[], it seems like I am also running into the problem that the @Lob annotation should indicate it is a BlobTypeDescriptor rather than a PrimitiveByteArrayTypeDescriptor. If that were done correctly then extractLoggableRepresentation would only return "

". Is there something I am missing with the @Lob annotation or is that a separate bug?

And @Gail if it helps, Payload is referenced in an Artifact entity with a @OneToOne annotations, while Artifact is references with a @OneToMany mapping:

  @OneToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL, orphanRemoval = true)
  @JoinColumn(name = "PAYLOAD_ID")
  private Payload payload;

  ...

  @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true)
  @JoinTable(name = "JOB_ARTIFACT")
  @MapKey(name = "type")
  private Map<String, Artifact> artifacts;
