Corregir el atributo "Ignorar InnerClasses"

Me gustaría corregir esta advertencia que me da cada construir esta salida:

Error:warning: Ignoring InnerClasses attribute for an anonymous inner class Error:(com.sun.jna.Native$1) that doesn't come with an Error:associated EnclosingMethod attribute. This class was probably produced by a Error:compiler that did not target the modern .class file format.

The consequence of ignoring Error:this warning is that reflective operations on this class will incorrectly Error:indicate that it is *not* an inner class.
