Betamax with Spring Boot throws Illegal use of nonvirtual function call

Question

I'm trying to setup a simple test in Groovy with Spock using Betamax:

class BetaMaxSpockTest extends Specification {

    @Rule
    public Recorder recorder = new Recorder()

    @Betamax(tape = "some_tape")
    def 'You shall pass'() {
        expect:
        true
    }
}

I'm also using Spring Boot so I have spring-boot-starter-parent as my parent in pom.xml:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.6.RELEASE</version>
</parent>

When I run above test I'm getting this error:

java.lang.VerifyError: (class: co/freeside/betamax/proxy/jetty/BetamaxProxy, method: super$3$getBean signature: (Ljava/lang/Class;)Ljava/lang/Object;) Illegal use of nonvirtual function call

Without Spring Boot on path it works fine. Looks like some versions problem. Anyone had similar issue?

Answer 1

I have found the solution. The problem was in wrong versions of jetty and httpclient. BetaMax requires versions shown below, while Spring's parent pom declares much newer versions.

Adding this two lines to properties in my pom.xml solved the issue:

<jetty.version>7.3.1.v20110307</jetty.version>
<httpclient.version>4.2.1</httpclient.version>

Anyway, thanks for your help!
