Johannes Ulfkjær Jensen commented on DIRMINA-529:
-------------------------------------------------

Hi,

I am not sure I am allowed to paste code into this comment field so I will try 
to describe another approach in words. Looking at the patch, it seems you can 
get the actual Class object for free, so why not just identify-compare that to 
the Class objects for the primitive types? You avoid the overhead of a native 
call, and being pure java, I think (pure speculation) that the JIT would have 
an easier time compiling it. This is obviously just an extreme mini 
optimization (compared to the patch) but I thought I would chime in regardless 
:)

> use isPrimitive() instead of comparing the string to a list of primitives
