Arquillian Wildfly Embedded Container - Unexpected Fatal Error

[eliasbalasis1]

When running Arquillian Wildfly Embedded Container,

if one of the deployed applications under test depends on spring-web framework

Arquillian embedded contained gives the error

Caused by: java.util.ServiceConfigurationError: javax.servlet.ServletContainerInitializer: Provider org.springframework.web.SpringServletContainerInitializer not found

The same problem does not occur when running with Managed Container.

My suspicion is about classpath resolution inside embedded container.

It looks like it is considering the jboss module loader only for classpath resolution.

I have attached a Maven project that reproduces the problem as soon as the "spring-web" dependency is enabled

I have posted this on both "Arquillian" and "Arquillian Development" groups under same title for convenience.

Any ideas?

Some more information,

This is reproducible on Wildfly 10.1.0 as well, which implies it is not Wildfly implementation issue, rather an Embedded container implementation issue.

Furthermore,

the problem occurs at java.util.ServiceLoader.LazyIterator.nextService() under Class.forName(cn, false, loader)

"loader" here is the JBoss module class loader instance

putting a break-point and

evaluating Class.forName("javax.servlet.ServletContainerInitializer", false, loader) generates "java.util.ServiceConfigurationError: javax.servlet.ServletContainerInitializer: Provider org.springframework.web.SpringServletContainerInitializer not found"

evaluating Class.forName("javax.servlet.ServletContainerInitializer", false, loader.getParent()) does not reproduce the error

This is clearly a problem with the Embedded container module class loader

Any thoughts anyone?
