Build Identifier: 

This could be an optional setting under Compiler-> Errors/Warnings

Reproducible: Always
Comment 1 Stephan Herrmann CLA 2010-07-04 18:30:27 EDT 
This warning would only be valid if the first access to the field
within the method is a write access. If state is preserved across 
method invocations it must stay as a field.

To me this sounds like a bit too much special-case analysis for the compiler.
