Alex Dettinger commented on CAMEL-11035:
----------------------------------------
I also hit a very similar stack trace using as below:
{code:java}
<extraOption>
<name>status</name>
<type>java.util.List<T></type>
</extraOption>
{code}
generates:
{code:java}

{code}
And indeed, I find the warning justified but the stack trace could be hidden.
Let me know if you would like that I to build a PR.
