I use Spring-Data-JDBC (not JPA) and want to set the fetch-size.
I know that the the classic

setFetchSize(int) method, but I have Spring-Data-JDBC repository:

i've been writing wirting a program in Spring Boot Web with JPA and i'm using a query to access some data with a 'contains' and 'ignorecase' filter, i've done this before in other programs and it has worked fine, but now i'm getting this error, i'm completely lost at this point since i can't find anything in google, i went really far down the rabbit hole looking as to why it happens and so far i don't see anything out of place in my code, the type of variable declared seems to be okay but as i've said, i'm lost. It's important to mention that for some reason when I do the query on my website for the first time, everything works fine, i get the proper results and all, but when I go back to home and try with another query (or even the same) i get the error.

I have seen various post describing that JPA EntityGraph allows to choose the graph at run time. And I am not entirely clear what this refers to.
Out of good faith and respect I would like to take this helpful article for reference: https://www.baeldung.com/jpa-entity-graph. (Most of JPA users might have gone through it already.)
The article quotes -
EntityGraph allows grouping the related persistence fields which we want to retrieve and lets us choose the graph type at runtime.
and again solidifies above statement in conclusion section.
In this article, we've explored using the JPA Entity Graph to dynamically fetch an Entity and its associations.
The decision is made at runtime in which we choose to load or not the related association.
As we see in the article (5.1) - EntityGraphs are defined as below using Annotations-

In the Baeldung article, Section 5 is only about various ways to define a graph with not much emphasis on the dynamic/non-dynamic nature of the definition itself.
In Section 5.1 the definition of the graph is static but this section is only about demonstrating how to define a graph which then will be used in typical cases when building the graph dynamically is not really necessary. This section shows an alternative to the older way of building HQL / JPA-QL queries with JOIN FETCH sections.
This worked fine for me be building under Java 8. Now under Java 17.01 I get this when I do mvn deploy.

You can use javax.persistence like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the javax.persistence component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
