I think this jar has been named this way for several releases, I'm not sure if there is a requirement for the file name to not include the version string.  Assigning to the seam lead for input.

I don't have any suggestion as this seam integration (aka Seam Deployers) library was always managed by AS team (ales justin precisely).

I think we need to know:

 - can it be renamed to follow -redhat-XX naming without any problem in integration == code doesn't contain hardcoded file name
 - is it built from sources when is EAP productized or is it downloaded from somewhere

I really want to have it named with -redhat-XX convention to stay consistent with the rest of jar files in EAP zip.

server/src/main/java/org/jboss/as/server/deployment/integration/Seam2Processor.java

contains a hard-coded 

public static final String SEAM_INT_JAR = "jboss-seam-int.jar";


final ModuleLoader moduleLoader = Module.getBootModuleLoader();
Module extModule = moduleLoader.loadModule(EXT_CONTENT_MODULE);
URL url = extModule.getExportedResource(SEAM_INT_JAR);
if (url == null)
  throw ServerMessages.MESSAGES.noSeamIntegrationJarPresent(extModule);


so at least this bit would have to be rewritten.

We have similar problem with resteasy-spring.jar.
Stuart came with solution which could be applied here too.
