Upgrade to Java 8 causes Orika mapper in unittest java.io.IOException: invalid constant type: 15 at 142

I have a project that I want to update the version from Java 1.7 to Java 1.8 but running the UnitTests all mapper tests are failing.

The project is using: SpringJUnit4ClassRunner

<dependency>
    <groupId>ma.glasnost.orika</groupId>
    <artifactId>orika-core</artifactId>
    <version>1.4.5</version>
</dependency>

For that part of the exception: nested exception is ma.glasnost.orika.MappingException: java.lang.RuntimeException: java.io.IOException: invalid constant type: 15 at 142 I found u.a this SO post: Reflections - Java 8 - invalid constant type
But I'm not sure if this is realy the problem, as I have no dependency on the 'javassist'.

Is this related to the same issue? How can I overcome that?

Solution

Your idea goes into the right direction.

the java.lang.RuntimeException: java.io.IOException: invalid constant type: 15 at 142 shows that the the application has problems with java 8 - as explained inn your link.

The ma.glasnost.orika mapper depends on javassist as you can see in the Stack Trace. This is a transitive dependency of orika.

You could use mvn dependency:tree -verbose to build a dependency tree. There you can look up the what library is depending eg on javassist and the exact version.

To use a javassist version that is Java 8 compatible use that dependency to overwrite the implicit dependency of orika:

  <dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.18.2-GA</version>
  </dependency>

But for this example it might by better to upgrade the orika version to 1.4.6 as this one is Java 8 ready.
