After moving the AS Runtime detector into as.core, the dtp dependencies were marked as optional. During some builds [1] DTP may not be present, and the AS handler runtime extension point will fail to resolve. The import of a dtp class inside JBossASHandler will cause the class to fail to load.

The solution is to isolate the dtp code and class references inside the DriverUtility, and ensuring only a wrapper exception is thrown (not a DTP exception).
