Run JAXB-popped fields through normal construction validation.
JAXB unmarshalling sets start, finish, level, and context directly, bypassing fromValues. In core/src/main/java/org/verapdf/component/AuditDurationImpl.java this can unmarshal negative or end-before-start durations; in core/src/main/java/org/verapdf/pdfa/results/LocationImpl.java it can skip context derefing such as 0000 (Abcd) becoming 0000 (Abcd in the persisted object. Use a JAXB post-unmarshall callback or adapter path to apply fromValues after field population, not only at construction.

Keep validationProfile consistent with JAXB-populated result fields.
The JAXB-deserialized ValidationResultImpl receives flavour and profileDetails, but validationProfile stays as the default profile because the no-argument/JAXB-accessible constructor does not bind it. This makes getValidationProfile(), fromValidationResult(), and stripPassedTests() use a profile that does not match the returned flavour/details, and existing XML tests only cover the default profile. Add a non-default-profile XML round-trip test, then restore the matching profile during unmarshalling or prevent profile-dependent APIs from being used on unmarshalled results.

JAXB unmarshalling property setters or field XML annotations setter semantics derived getter property final field
💡 Result:
In Jakarta XML Binding (JAXB), the unmarshalling process depends heavily on how the class is annotated and the configured access type [1][2][3]. Whether JAXB uses setters or direct field access is determined by these factors: Access Type and Semantics JAXB uses XmlAccessorType to control how it interacts with class members [1][3]. - XmlAccessType.FIELD: JAXB ignores properties (getters/setters) and directly accesses the fields, even if they are private [4][5]. If you place annotations on your setters, they will be ignored or may even cause configuration conflicts if the corresponding field is also annotated [4][5][6]. - XmlAccessType.PROPERTY (or default PUBLIC_MEMBER): JAXB prioritizes JavaBean property access (getter/setter pairs) [1][3]. If this mode is active, JAXB will attempt to use the setter method to inject unmarshalled values [5][7]. Forceing Setter Usage To ensure JAXB uses your setter methods (e.g., for custom validation logic), follow these practices: 1. Do not use @XmlAccessorType(XmlAccessType.FIELD) [7]. 2. Place your JAXB annotations (e.g., @XmlElement, @XmlAttribute) on the getter method (or the setter, but not both) [5][7]. 3. Ensure you have a matching getter/setter pair; JAXB generally requires both to identify a property, though it specifically uses the setter to update the value during unmarshalling [7][8]. Final Fields JAXB requires the ability to set the value of a property. Consequently, final fields are generally incompatible with JAXB unmarshalling because they cannot be modified after the object's constructor has finished. If a class requires unmarshalling, those fields must typically be mutable (non-final). Derived Properties Derived properties (properties that have a getter but no corresponding field or setter) are generally ignored by the unmarshaller because JAXB has no way to "set" their value [8]. If you need to map a derived-style property that requires transformation, you can use an @XmlAdapter, which provides a way to convert complex logic into a format JAXB can handle [6]. Collections For collection types, JAXB behavior is specific: it often checks if the collection is null via the getter and initializes it if necessary, then uses standard collection methods (like.add) or the setter to populate it [8]. It does not always replace the entire collection instance via the setter, which is a common point of confusion for developers expecting setter-only behavior [8].

Provide mutable JAXB storage for derived processor result properties.
XML unmarshalling cannot restore state through derived getters: getResultSet() returns taskResults.values(), so tasks cannot be bound into the result map, and getFeaturesReport() only derives a wrapper from featuresResult, so feature data is lost. Add read/write JAXB-backed storage and rebuild the derived results. Keep task exception reconstruction in mind as well: the marshalled taskException element is derived from the final exception field, while unmarshalling only writes primitive fields and duration, so unexpected exception text can be written but not read back unless the exception state is stored as well.

Java Collections.unmodifiableList null NullPointerException documentation
💡 Result:
The Java method Collections.unmodifiableList does not inherently throw a NullPointerException when processing null elements [1][2]. Because it returns an unmodifiable view (a wrapper) of the provided backing list, it permits null elements if the underlying list supports them [1][2]. This behavior is distinct from the unmodifiable collections created by factory methods like List.of or Collectors.toUnmodifiableList, which are truly immutable data structures and explicitly disallow null elements, throwing a NullPointerException if they are used [3][4][5]. Key distinctions to note: 1. Unmodifiable View (Collections.unmodifiableList): This creates a "read-only" view. Any attempt to modify the returned list directly (e.g., using add or remove) will result in an UnsupportedOperationException [6][7][2]. However, because it is merely a view, changes to the original backing list remain visible through the unmodifiable wrapper [3][5]. It allows nulls if the backing list allows nulls [1][2]. 2. Immutable Collections (List.of): Introduced in Java 9, these are truly immutable data structures, not views [3][5]. They do not allow null elements under any circumstances [3][8]. In summary, if you are encountering a NullPointerException, it is likely due to the specific implementation of the backing collection being used, or because you are using a different API (like List.of) that prohibits nulls, rather than the unmodifiable view itself [3][5][1].

Java 8 OpenJDK src/java.base/share/classes/java/util/Collections.java unmodifiableList null
💡 Result:
In Java 8, as in other versions of Java, the behavior of java.util.Collections.unmodifiableList regarding null values can be categorized into two distinct aspects: 1. Handling of the 'list' argument: The Collections class methods, including unmodifiableList, explicitly document that they throw a NullPointerException if the collection (the list) provided as an argument is null [1]. 2. Handling of null elements within the list: The list returned by Collections.unmodifiableList is an unmodifiable view of the original backing list [1][2]. It does not impose its own restrictions on the contents of that list; instead, it delegates all operations to the backing list [1][2][3]. Because null is considered a valid value for any reference type in Java, the returned unmodifiable list permits the presence of null elements if, and only if, the underlying backing list permits them [4][3][5]. In summary, passing a null list to Collections.unmodifiableList will result in a NullPointerException, while the presence of null elements inside a non-null list passed to the method is permitted or prohibited based entirely on the capabilities of the original backing list [1][3].

Make the CheckImpl no-argument path null-safe.
JAXB uses the private no-argument constructor to create a CheckImpl instance, which passes null for errorArguments. Collections.unmodifiableList(null) throws NullPointerException before JAXB can populate the field, so unmarshalling a report with a check element fails unless errorArguments is omitted on line 56. Use Collections.emptyList() in the no-argument constructor, or normalise null before calling Collections.unmodifiableList, and preserve the returned unmarshalled empty list on JAXB field assignment.

Make the private no-argument constructor in CheckImpl null-safe by initializing
errorArguments to Collections.emptyList(), or normalize null before wrapping it
with Collections.unmodifiableList. Ensure JAXB can instantiate and populate the
field while preserving an unmarshalled empty list assigned to errorArguments.
