    ConverterNotFoundException after upgrading Spring to 4.3.4

    Stack Overflow | 5 months ago | Zipper
    org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [org.javatuples.Pair<?, ?>] to type [my.namespace.Category] And it's for this repo call. @Query("select new org.javatuples.Pair(cpc.category, count(*)) from UnlinkedProductCategorization cpc where cpc.myField = ?1 group by cpc.category") Collection<Pair<Category,Long>> countByCategoryForContainer(MyFieldType selfContainer); Nothing in this repo has changed, and if we revert back to everything works. We have other cases where we use select new org.javatuples.Pair(someEntityHere, count(*)) that still work, so I can't figure out why the upgrade would have broken it. And why it thinks it should try to convert the Pair to a Category, which really doesn't make sense. Here's the call stack just after our last method org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [org.javatuples.Pair<?, ?>] to type [com.siftit.domain.core.category.Category]
