I've already asked this question on stackoverflow, but so far no answer.

My setup: WebSphere Liberty 8.5.5.9 Kernel, (Oracle) JDK 1.8.0_74, Eclipse Mars with Liberty Tools, OS is Windows 7 (64 Bit). I've got a simple Maven project (modified from an example i found, the code is on GitHub) consisting of a facelet and a WindowScoped bean, i'm using Deltaspike 1.6.0 The application starts up, but the Eclipse console shows a couple of warnings:

 [WARNUNG ] Could NOT lazily initialize session context because NO active request context
 [WARNUNG ]

Whats more, there are entries in the ffdc directory, the summary file containing

 java.lang.NoClassDefFoundError com.ibm.ws.webbeans.impl.scanner.LibertyScannerService.loadBeanClasses 553

So something is not quite right here.

The real trouble starts after adding JPA - Eclipse project facet, persistence.xml, OpenJPA dependency (provided) - and a simple stateless session bean that basically does nothing. The application doesn't start up anymore, the console prints

 [11.04.16 08:12:27:624 MESZ] 00000019 org.apache.webbeans.context.LibertyContextsService           W Could NOT lazily initialize session context because NO active request context

I've put a complete set of logs (including FFDCs) on GitHub as well: link text

I've also tested a switch from Deltaspike to CODI (Release 1.0.6), the application runs just fine without any errors or even warnings.

We also got a - way more complex - application running on WebSphere 8.0 using Deltaspike. There are a couple of info messages on startup in the console, but apart from that no problems.

Thanks for any hints,

Steffen
