Unable to instantiate AttributeConverter: root cause of exception hidden

Description

I get this expection when using Converter class with autoApply = true:
Caused by: org.hibernate.AnnotationException: Unable to instantiate AttributeConverter [biz.mbisoftware.fn.datatypes.DeliveryDateType$Converter]

Unfortunately the exception thrown by attributeConverterClass.newInstance() is hidden / not used.
So I get no hint what's the cause of the problem.

Environment

WildFly 8.0.0.CR1 on Solaris SPARC 10 using Oracle JDK 1.7.0_45.
