             Summary: DeploymentExceptionHandler can sometimes pass null to transformers
                 Key: ARQ-2175
                 URL: https://issues.jboss.org/browse/ARQ-2175
             Project: Arquillian
          Issue Type: Bug
          Components: core
    Affects Versions: 1.3.0.Final
            Reporter: Matej Novotny


In some rare cases {{DeploymentExceptionHandler}} can pass null value to transformers, which isn't really useful.

This can happen when the exception is {{DeploymentException}} which has no cause (or has itself set as cause). E.g. [this code|https://github.com/arquillian/arquillian-core/blob/1.3.0.Final/container/impl-base/src/main/java/org/jboss/arquillian/container/impl/client/container/DeploymentExceptionHandler.java#L106-L108] can yield {{null}}.

I came across this in combination with [wildfly-arquillian|https://github.com/wildfly/wildfly-arquillian] and certain Arq. interceptor ordering (so that this exception handler was called first and the exception wasn't wrapped yet).
