> In Forge, exceptions are wrapped by Javassist to prevent CCEx when exceptions traverse the addon boundaries.
> But this wrapping is done in a way that the hierarchy of exceptions is not treated correctly - seems that it's only getting to the bottom of causes, dropping the important context and linked information (e.g. InvocationTargetException's target, JAXB's linkedException, ...).
> One example:
> Shown exception:
> org.javassist.tmp.java.lang.Exception_$$_javassist_3c6f95f1-dabc-4ae0-b23a-7fe4056dfdf3: null
> 	at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:197)
> 	at org.jboss.modules.ConcurrentClassLoader.performLoadClassUnchecked(ConcurrentClassLoader.java:443)

> 	at org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:373)

> Actual exception:
> javax.xml.bind.JAXBException
>  - with linked exception:
> [java.lang.ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory from [Module "_DEFAULT_:259a118d-0dc2-4d39-bce5-46b4de8d118b_84602e04-6399-449b-89b8-874e07e9bcf9" from AddonModuleLoader]]
