started getting Class Not Found Exception randomly

hey guys. when i start my spring boot app i get this error: java.lang.ClassNotFoundException: lt.mycompany.myapp.service.XmlParserUtil. The thing is that XmlParserUtil was used just fine in this app. Now im adding new functionality, and for some reason i cant even start my app. XmlParserUtil looks like this:

@Service
public class XmlParserUtil {
    private StatementDocumentWrapper convertToV053s02(InputStream is) throws JAXBException {
        JAXBContext jaxbContext = JAXBContext.newInstance(ObjectFactory.class);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        Document doc = ((JAXBElement<Document>) jaxbUnmarshaller.unmarshal(is)).getValue();
        StatementDocumentWrapper sDoc = new StatementV053S02DocumentWrapper(doc);
        return sDoc;
    }
    private StatementDocumentWrapper convertToV052s02(InputStream is) throws JAXBException {
        JAXBContext jaxbContext = JAXBContext.newInstance(lt.mycompany.iso20022.camt.v052s02.ObjectFactory.class);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        lt.mycompany.iso20022.camt.v052s02.Document doc = ((JAXBElement<lt.mycompany.iso20022.camt.v052s02.Document>) jaxbUnmarshaller.unmarshal(is)).getValue();
        StatementDocumentWrapper sDoc = new StatementV052S02DocumentWrapper(doc);
        return sDoc;
    }
    public StatementDocumentWrapper InputStreamToDocument(InputStream is) throws JAXBException, IOException {
        byte[] bytes = is.readAllBytes();
        StatementDocumentWrapper sd;
        try {
            sd = convertToV053s02(new ByteArrayInputStream(bytes));
        } catch (UnmarshalException e) {
            sd = convertToV052s02(new ByteArrayInputStream(bytes));
        }
        return sd;
    }
}

@Service
public class XmlParserUtil {
    private StatementDocumentWrapper convertToV053s02(InputStream is) throws JAXBException {
        JAXBContext jaxbContext = JAXBContext.newInstance(ObjectFactory.class);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        Document doc = ((JAXBElement<Document>) jaxbUnmarshaller.unmarshal(is)).getValue();
        StatementDocumentWrapper sDoc = new StatementV053S02DocumentWrapper(doc);
        return sDoc;
    }
    private StatementDocumentWrapper convertToV052s02(InputStream is) throws JAXBException {
        JAXBContext jaxbContext = JAXBContext.newInstance(lt.mycompany.iso20022.camt.v052s02.ObjectFactory.class);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        lt.mycompany.iso20022.camt.v052s02.Document doc = ((JAXBElement<lt.mycompany.iso20022.camt.v052s02.Document>) jaxbUnmarshaller.unmarshal(is)).getValue();
        StatementDocumentWrapper sDoc = new StatementV052S02DocumentWrapper(doc);
        return sDoc;
    }
    public StatementDocumentWrapper InputStreamToDocument(InputStream is) throws JAXBException, IOException {
        byte[] bytes = is.readAllBytes();
        StatementDocumentWrapper sd;
        try {
            sd = convertToV053s02(new ByteArrayInputStream(bytes));
        } catch (UnmarshalException e) {
            sd = convertToV052s02(new ByteArrayInputStream(bytes));
        }
        return sd;
    }
}

if running in ide and it's intellij sometimes this happens, try file -> invalidate caches... -> invalidate and restart .

thanks. im doing it right now. i was also thinking would doing smth with gradle help? idk, maybe refreshing gradle project or smth? nope, still the same 😦

Given the context of the error and the line at org.springframework.boot.devtools.restart.RestartLauncher.run(RestartLauncher.java:49), it is likely that the Spring Boot DevTools is causing the issue. Try disabling Spring Boot DevTools. In your build.gradle comment out the devtools dependency: implementation 'org.springframework.boot:spring-boot-devtools' If you want to use DevTools then just exclude this package: spring.devtools.restart.exclude=lt/mycompany/paymentimport/service/**. Sometimes, cleaning and rebuilding the project can resolve issues related to outdated or corrupt class files. gradle clean build

Alternatively it could theoretically be some verifier issue (some dependency class being missing and verification not completing because of that). You could try to check this by adding -Xverify:none to the JVM args but only do that for testing and remove it afterwards
