Incompatible magic value 0

I'm developing java maven project in STS (based on Eclipse Juno 3.8.2) and I'm getting following error:

java.lang.ClassFormatError: Incompatible magic value 0 in class file org/eclipse/jdt/internal/junit4/runner/JUnit4TestReference

I think it have something to do with mixed Java versions, but I'm not able to solve it, probably I missed something.

Full stacktrace is:

I found out, that there is a problem only when I'm trying to run JUnit tests, my project is running fine. I tried to check run configuration and it seems it's ok. I checked project facets too, and everything seems to be ok there too...

I got this error messages but nothing worked for me. My problem probably is related to the way I move new classes from dev to production. I created the new class on Dev and copied it over to Production, not the .war file, at the end the class owner on tomcat folder was "root", not "tomcat", "chown" to tomcat fixed the problem.

same here solved by simply clean and rebuild the project again

in my case this error happened just when i change a super class of the mentioned class;

the class mentioned on my stacktrace is a class in my project not in specific library like yours

org/eclipse/jdt/internal/junit4/runner/JUnit4TestReference

hope that help you

It seems, that is some general problem with STS (based on Eclipse Juno 3.8.2).

I tried the simplest possible test and it's not working too:

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>net.betlista</groupId>
    <artifactId>tests-sts</artifactId>
    <version>0.0.1-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>3.2.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.2.2.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>3.2.2.RELEASE</version>
        </dependency>
    </dependencies>

</project>

test class

package net.betlista.tests.sts.junit;

import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration( classes = { JavaConfig.class } )
public class CalculatorTest {

    @Autowired
    Calculator calculator;

    @Test
    public void addTest() {
        final int a = 10, b = 20;
        Assert.assertEquals( a + b, this.calculator.add( a, b ) );
    }

}

configuration class

package net.betlista.tests.sts.junit;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class JavaConfig {

    @Bean
    public Calculator getCalculator() {
        return new Calculator();
    }

}

service class

package net.betlista.tests.sts.junit;

import org.springframework.stereotype.Service;

@Service
public class Calculator {

    int add( final int a, final int b ) {
        return a + b;
    }

}

and I'm getting same error in STS (3.8.2), while in STS (4.2.2) everything works fine.

Despite having 1.7.0_17 on the command line I think your Eclipse is running on an older version of java. To determine what version of java Eclipse is running on see:

Find out what JVM Eclipse is running on

Then to change the version of java Eclipse is running on see:

http://wiki.eclipse.org/Eclipse.ini#Specifying_the_JVM

Hope that helps.
