- Utils.getStructType: @parameterized on StaticArrayN struct fields now correctly emits "foo[N]" instead of collapsing to "foo[]". Throws RuntimeException on ClassNotFoundException instead of silent fallback; extractStaticArraySize now takes Class<?> and validates that the class is a generated StaticArrayN subclass (rejects raw StaticArray.class with a guidance message). - Utils.getParameterizedTypeName: build canonical ABI names for nested arrays via the new getArrayElementTypeName helper, which recurses on TypeReference rather than collapsing the inner type to a Class. The old path produced non-canonical strings like "staticarray2[]". - DefaultFunctionReturnDecoder.getDataOffset: include DynamicStruct in the dynamic-offset detection. The hand-rolled OR-chain was missing it, causing DynamicStruct return values to be decoded from the wrong offset. - DynamicArray.getTypeAsString: throw when an empty array's component type is the generic DynamicStruct/StaticStruct base or a raw Array subclass — Java type erasure cannot recover the inner element type in those cases. Concrete StructType subclasses still resolve through Utils.getStructType. - Utf8String.bytes32PaddedLength: guard against null value, matching the null-tolerance already in equals()/hashCode(). - Array: remove the unused getNativeValueCopy() method. It was dead code in this PR (zero callers) and only unwrapped one level, so nested arrays/structs still contained ABI Type objects rather than native values. - UtilsTest: positive/negative cases for issue tronprotocol#20, DynamicArray regression guard, and canonical nested array type names (uint256[2][], uint256[2][2]). - EventEncoderTest: nested static array method signature. - DynamicArrayTest: empty concrete struct array (allowed), empty raw Array subclass (throws), empty generic struct array (throws). - Utf8StringTest: bytes32PaddedLength with null value. - CustomErrorTest: assert parameter count before per-element comparison; the previous loop could pass silently if getParameters() returned fewer elements than expected. - TridentAbiEncodeDecodeCompatibilityTest.isSignedIntOutOfRange: treat bare `int` as ABI alias for int256.
