Arquillian test won't run when code has java 8 lambda expression - java-8

Question

I have an Arquillian test that fails to run if either my test method or the EJB my test is invoking uses lambdas. The test doesn't even get far enough to run, looks like it fails on arquillian initialization. For example, putting this
Stream.of("one", "two", "three").map(String::new);
into my test method results in the following exception when executing as a junit test inside eclipse.

I'm using Arquillian 1.1.8.Final and JBoss shrinkwrap resolver 2.2.0

Answer 1

Removing the arquillian-suite-extension as a dependency fixed the issue, even though I wasn't using it
<dependency>
<groupId>org.eu.ingwar.tools</groupId>
<artifactId>arquillian-suite-extension</artifactId>
<version>1.1.2</version>
<scope>test</scope>
</dependency>

Answer 2

To add to John Ament's comment, because it wasn't immediately obvious to me and this issue still persists:
When using arquillian-suite-extension you need to set the version of org.reflections/reflections to exactly 0.9.9 in your pom.xml. Neither a version higher or lower than that worked for me.
This is the entry required in your pom.xml:
<dependency>
<groupId>org.reflections</groupId>
<artifactId>reflections</artifactId>
<version>0.9.9</version>
</dependency>
