运行Pax检查时的IllegalStateException

Question

当运行Pax考试时，我得到了以下异常。我的配置只包含一个来自文件系统、junit和felix的包。知道为什么会这样吗？

java.lang.IllegalStateException: Stream handler unavailable due to: null

编辑:我使用的是Pax Exam 2.5.0，下面是我的配置方法。

@Configuration
public Option[] config() {
    return options(
            bundle("file:/home/nufail/mybundle.jar"),
            junitBundles(),
            felix().version("3.2.2")
    );
}

对于版本4.9.2，通过向maven添加以下依赖项解决了该问题

<dependency>
   <groupId>org.ops4j.pax.exam</groupId>
   <artifactId>pax-exam-link-mvn</artifactId>
   <version>4.9.2</version>
   <scope>test</scope>
</dependency>
