Use @Param for query method parameters, or when on Java 8+ use the javac flag -parameters.; nested exception is java.lang.IllegalStateException: For queries with named parameters you need to use provide names for method parameters. Use @Param for query method parameters, or when on Java 8+ use the javac flag -parameters.
