FreeMarker template error in JPA Report (Windup 2.4.0.Final)
I'm using Windup 2.4.0.Final to analyse a Seam 2.2.5 (EAP) web app that runs on JBoss EAP 5.2.
I tried using different options for input: EAR package and --sourceMode.
I ran windup in a Windows Box with Java SE 7 and 8.
The windup generated the final report but the JPA report page show an exception error in the JPA Entities section:
FreeMarker template error (DEBUG mode; use RETHROW in production!): The following has evaluated to null or missing: ==> entity.entityName [in template "reports/templates/jpa.

refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing. (
These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)?? ---- ---- FTL stack

Have some one experienced this exception for JPA report?
What is relevant to check in my environment to help investigate this issue? Is the some log output? Is there a debug mode in Windup execution?
