Tests Updated

TEST.groups
Add java/util/Arrays to valhalla_adopted, bringing the Arrays test directory into the Valhalla-adopted test group.

AsList.java
Add value-oriented object-array datasets: an @AsValueClass record, boxed Integer, LocalDate, and Optional. This extends the existing iterator contract test to ensure Arrays.asList() behaves the same for value-capable elements, including assertSame on iteration.

ArrayObjectMethods.java
Add an @AsValueClass record and extend the random object/nested-object generators so value objects and value-object arrays participate in the existing toString, deepToString, hashCode, deepHashCode, and deepEquals coverage. This broadens mixed-content object-array coverage rather than adding a separate value-only test path.

ArraysEqCmpTest.java
Add an @AsValueClass Point type and a corresponding ArrayType so the existing Arrays.equals, Arrays.compare, and Arrays.mismatch matrix now runs on value-object arrays too. The object-array same-element tests were also generalized to use the ArrayType abstraction instead of assuming Integer[].

Big.java
Add a large-array Point[] path using an @AsValueClass record. This extends the existing huge-array binarySearch and range-sort coverage to value-object arrays.

CopyMethods.java
Add Point, LocalDate, and Optional to the reflective copy/copyOfRange test matrix, plus the coercion and cloner wiring needed for those types. This extends the existing generic copy-method framework to value-capable reference types.

Correct.java
Add an @AsValueClass Point type plus default-sort and comparator-sort subrange tests for Point[], using the existing “compare against reference sort” approach.

Fill.java
Add an @AsValueClass array target and verify existing exception behavior when filling it with the wrong type or with an out-of-bounds range.

HashCode.java
Add an @AsValueClass Point test that checks Arrays.hashCode(Point[]) is equal for equal value-object arrays and stable across repeated calls.

SetAllTest.java
Add Point[] coverage for Arrays.setAll and Arrays.parallelSetAll, including normal generation cases and the existing null-argument exception checks.

Sorting.java
Add an @AsValueClass Point sort path to the main sorting test suite. This extends the existing object-sort coverage to value objects for both natural ordering and comparator ordering.

StreamAndSpliterator.java
Extend the existing null-array and bad-range exception tests to additional reference-array types: Integer[], Long[], Optional[], and LocalDate[]. This broadens object-array coverage for Arrays.stream, Arrays.spliterator, and Spliterators.spliterator.

largeMemory/ParallelPrefix.java
Add an @AsValueClass VInt type and extend the existing parallelPrefix framework to cover value-object arrays, including normal prefix computation plus NPE/IAE/AIOOBE checks.

Tests With No Change

FloatDoubleOrder.java
No change -- primitive-only float/double ordering test.

SortingIntBenchmarkTestJMH.java, SortingLongBenchmarkTestJMH.java
No change -- primitive-array JMH benchmarks.

SortingNearlySortedPrimitive.java
No change -- primitive-only nearly-sorted coverage.

TimSortStackSize.java, TimSortStackSize2.java
No change -- TimSort stack-shape regression tests over existing Integer[] inputs.
