Spring Batch - unable persist reader type

after upgrading to Spring Batch 3.0.2 faced the following issue: chunk step fails trying to persist reader object which is not JPA Entity and not Serializable.
#Autowired
protected PlatformTransactionManager transactionManager;
#Autowired
protected JobRepository jobRepository;
[...]
#Bean
#JobScope
public Step processFileStep() {
return new StepBuilder("process-file", jobRepository)
.<Row, Matching>chunk(chunkSize, transactionManager)
.reader(reader())
.processor()
.writer(writer())
.build();
}
Row type here is org.apache.poi.ss.usermodel.Row which is passed by custom Apache POI Excel item reader. transactionManager and jobRepository are autoconfigured by Spring Data JPA.
On this step the following exception occurs:
java.lang.IllegalArgumentException: Not an entity [class org.apache.poi.xssf.usermodel.XSSFRow]

Before this updage from Spring Batch 2.6.6 to Spring Batch 3.0.2 chunk() method did not have transactionManager parameter and this code worked as intended.
It seems like Map-based job repository should work in this case but it's not a production-ready solution.
Is there any way to use org.apache.poi.ss.usermodel.Row (or any other non-JPA object) as reader output with newer Spring Batch version with persistent storage?
Thanks in advance.

By debugging Spring Batch source code found that JpaItemWriter tries to persist list of Row's instead of Matching ones.
Found a silly mistake in my code:
#Bean
#JobScope
public Step processFileStep() {
return new StepBuilder("process-file", jobRepository)
.<Row, Matching>chunk(chunkSize, transactionManager)
.reader(reader())
.processor()
.writer(writer())
.build();
}
this part is missing an actual processor.
So my POI list of Row's passed directly to JPA writer. I've made my processor dummy for testing purposes and never checked that it was actually called.
Correct Step code is
#Bean
#JobScope
public Step processFileStep() {
return new StepBuilder("process-file", jobRepository)
.<Row, Matching>chunk(chunkSize, transactionManager)
.reader(reader())
.processor(processor())
.writer(writer())
.build();
}
Can't believe it couldn't find this issue for at least a few days.

Kafka Streams Binding: Store (prod-id-count-store) not available to Streams instance

Can you please tell what I'm doing wrong, because I've wasted 2 days and have no ideas.

The fix is in the main branch, but not 3.2.x yet. However, you should be able to workaround the issue by setting:
spring.cloud.stream.kafka.streams.binder.configuration.application.server=<server>:<port>

I think this is related to this issue: https://github.com/spring-cloud/spring-cloud-stream/issues/2523
Could you try it against the latest 3.2.x snapshot of the binder? (3.2.6-SNAPSHOT). We will do a release soon for this.
You just need to update the binder dependency - spring-cloud-stream-binder-kafka-streams (to 3.2.6-SNAPSHOT).

JMockit Version: 1.47
Jupiter JUNIT Version: 5.3.2
IntelliJ Version: 2019.1 Ultimate
Can anyone help.

Found the issue. The issue is related to the Jmockit version that was used. The issue got resolved after I reverted the JMockit version to 1.42,
<dependency>
<groupId>org.jmockit</groupId>
<artifactId>jmockit</artifactId>
<version>1.42</version>
<scope>test</scope>
</dependency>
The issue is closely related to constructing instrumentation that can be used to reform classes to mock objects. For JMockit to run, the Jmockit JAR needs to be passed as a java agent. Prior to 1.43, If the java agent is not passed, JMockit library searches the project's dependencies and adds this to the VM object automatically. After 1.42, It was deemed by JMockit developers that this way of finding the JAR is not a good standard and is removed completely. Thereby requiring java agent to be passed manually.
Here are some reference links related to the issue,
https://github.com/jmockit/jmockit1/issues/540#issuecomment-444316617
https://github.com/jmockit/jmockit1/issues/546
https://github.com/jmockit/jmockit1/issues/568
The solution to resolving such a problem would be to
Move to version 1.42 or
Follow this sample from JMockit developers and do the same.

Junit 5 Integration Test Docker

I am trying to run an integration test that creates an InfluxDB docker instance. I am using Junit5-docker. I don't see anything in the documentation about specifying a container ID. The example does exactly what I am doing as far as I can tell. Does anyone know what I'm doing wrong?
This is the test file:
import static org.junit.jupiter.api.Assertions.assertEquals;
import com.github.junit5docker.Docker;
import com.github.junit5docker.Port;
import com.github.junit5docker.WaitFor;
import com.******.healthmonitor.HealthMonitorSvcApplication;
import org.influxdb.InfluxDB;
import org.influxdb.InfluxDBFactory;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.context.annotation.Profile;
#Profile("medium-test")
#SpringBootTest(classes = HealthMonitorSvcApplication.class)
#Docker(image = "influxdb", ports = #Port(exposed = 8086, inner = 8086), waitFor = #WaitFor("Listening on HTTP"))
class MediumTests {
#BeforeEach
void setup() {
}
#Test
void endToEndTest() {
InfluxDB db = InfluxDBFactory.connect("http://localhost:8086", "root", "root");
db.ping();
assertEquals(true, true);
}
}
The output when I run endToEndTest is:

Looks like you have Jersey client classpath conflict.
Try to solve it first.
For example, see this question java.lang.NoSuchMethodError: javax.ws.rs.core.UriBuilder.resolveTemplate() using jaxrs cxf implementation
or AbstractMethodError using UriBuilder on JAX-RS
If you use Maven and Intellij IDEA there's a Maven Helper plugin that helps to resolve conflicts:
https://plugins.jetbrains.com/plugin/7179-maven-helper
java.lang.NullPointerException: containerId was not specified seems like a bug in the Docker plugin. But it's not your main issue.
From the code it looks like the container was never started, but the plugin still tries to stop it:
https://github.com/FaustXVI/junit5-docker/blob/242ed570e29e824bbf147eafc74d272e445461d5/src/main/java/com/github/junit5docker/DockerExtension.java#L120

Spring Boot Integration Testing

I have been trying to write a integration test for a small Spring boot Project that I have written but for some reason seem unable to get integration tests to work. Here is what I am trying to do:
package au.azzmosphere.integration;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
#RunWith(SpringJUnit4ClassRunner.class)
#SpringBootTest(classes = {IntegrationTestConfiguration.class})
public class TestIntegration1 {
#Test
public void testDummy() {
}
}
the configuration class has the following:
package au.azzmosphere.integration;
import au.azzmosphere.configuration.RobotAppConfig;
import org.springframework.context.annotation.Configuration;
#Configuration
public class IntegrationTestConfiguration extends RobotAppConfig {
}
The code is consistently getting the following errors when I try to run the Integration Test from IntelliJ
14:54:01.537 [main] DEBUG org.springframework.test.context.junit4.SpringJUnit4ClassRunner - SpringJUnit4ClassRunner constructor called with [class au.azzmosphere.integration.TestIntegration1].
14:54:01.542 [main] INFO org.springframework.test.context.TestContext - #ContextConfiguration not found for class [class au.azzmosphere.integration.TestIntegration1].
14:54:01.549 [main] INFO org.springframework.test.context.TestContextManager - #TestExecutionListeners is not present for class [class au.azzmosphere.integration.TestIntegration1]: using defaults.
From gradle the following is returned

Worked it out, :) The problem was that I did not have any TransactionDefinition defined because I didn't use it. The default SpringBoot annotation attempts to inject it. The answer was to use #TestExecutionListeners({DependencyInjectionTestExecutionListener.class}) which overrides the defaults and gets things going.
