Java 11 junit 木星断言抛出

Question

I try to migrate from Java 8 to 11 and get an error in my test class that I don't understand.

My failing (groovy) test is:

@SpringJUnitConfig
class TestSpringBeanScopeChecker {
    @Autowired
    ApplicationContext ctx

    @Test
    void testSingletonFail() {
        Assertions.assertThrows(IllegalStateException.class) {
            SpringBeanScopeChecker.check(ctx, DummyPrototype.class, BeanDefinition.SCOPE_SINGLETON)
        }
    }
}

The SpringBeanScopeChecker:

public class SpringBeanScopeChecker {

    private SpringBeanScopeChecker() {}

    public static void check(ApplicationContext ctx, Class<?> type, String scope)
            throws IllegalStateException {

        AbstractApplicationContext actx = (ctx instanceof AbstractApplicationContext) ? 
                ((AbstractApplicationContext) ctx) : 
                new StaticApplicationContext(ctx);

        ConfigurableListableBeanFactory factory = actx.getBeanFactory();

        for (String key : ctx.getBeanNamesForType(type)) {
            BeanDefinition definition = factory.getMergedBeanDefinition(key);

            if (!scope.equals(definition.getScope())) {
                throw new IllegalStateException(
                        "Every spring bean "
                                + "must be request scoped in the bean configuration. The current scope is: "
                                + definition.getScope());
            }
        }
    }
}

So for the test I'm expecting a IllegalArgumentException . And this is working fine with Java8 . When I switch to Java11 and execute the test I get this error:

[ERROR] testSingletonFail  Time elapsed: 0.009 s  <<< FAILURE!
org.opentest4j.AssertionFailedError: Unexpected exception type thrown
==> expected: <java.lang.IllegalStateException> but was: <java.lang.AbstractMethodError>

In case someone else has the same problem I write down the solution for this. The problem was misconfiguration of the groovy-eclipse-compiler and groovy-eclipse-batch .

My groovy version is managed by spring-boot and I didn't update the groovy-eclipse-batch according to the groovy.version from the spring-boot pom.

According to this issue on github :

You have to compile with groovy-eclipse-batch and groovy runtime in the same version. groovy-eclipse-batch and groovy runtime should be matched up. Eg batch 2.5.10-0x and runtime 2.5.10 or batch 3.0.1-0x and runtime 3.0.1 .
