Hello,

I use Arquillian for Integration Tests, and I intermittently get this kind of stacktrace:

exportDatabase(fr.utc.dsi.evote.tests.VoteITCase)  Time elapsed: 0.023 sec  <<< ERROR!

The EJB is declared like this in VoteITCase: @EJB JarExportBean exportBean;

This error does not occur systematically - when the injection works the test runs fine.

Before I try to make a reproducible simple testcase, has someone already seen this problem or has an idea on how to solve it ?

Environment:

     - Wildfly 9.0.2 (also occurs with 9.0.1.Final)

     - Arquillian BOM 1.1.10.Final (also occurs with versions between 1.1.6.Final and 1.1.10.Finall)

     - org.wildfly.arquillian wildfly-arquillian-container-managed 1.0.1.Final

I'm sorry if this is the wrong forum, I'm unable to determine if this is caused by Arquillian or the application server itself.

Thanks,

Christophe
