This issue still exists in the codebase.

The problem occurs because the JBossRulesRouter code has a global cache of the Rule Bases and these rule bases include generated code (ShadowProxy) which extend and reference the QS DTOs.

When the QS is redeployed the DTOs are reloaded with a different classloader and these classes are no longer assignable to the generated code.
