【问题描述】：

我的表中有一个下面的 UDT

productsinfo FROZEN<productsinfo>

这是 productsinfo 的 UDT 架构

"owned_product_details" map<text, FROZEN<list<FROZEN<productdetails>>>>,
"available_product_details" map<text, FROZEN<list<FROZEN<productdetails>>>>

产品详情UDT有一些文本字段

当我尝试使用 Java 插入值时，它会抛出异常

java.lang.NullPointerException: at index 1

在调试时我发现了这个

suppressedExceptions    Collections$UnmodifiableRandomAccessList<E>  (id=317)   

以下是Java中的实体类

@Column("productsinfo")
@CassandraType(type = DataType.Name.UDT, userTypeName = "productsinfo")
private ProductsInfo productsInfo;

@Column("owned_product_details")
@CassandraType(type = DataType.Name.MAP, typeArguments =  DataType.Name.TEXT, DataType.Name.LIST )
private Map<String, List<ProductDetails>> ownedProductDetails;

@Column("available_product_details")
@CassandraType(type = DataType.Name.MAP, typeArguments =  DataType.Name.TEXT, DataType.Name.LIST )
private Map<String, List<ProductDetails>> availableProductDetails;

https://jira.spring.io/browse/DATACASS-651 解决了这个问题，你可以在更新到某个版本 >=2.2 RC1 后重试吗？
