Hmmm, not sure this is an answer, but the compiler does quite
interesting things with a public static final fields.
Effectively the compiler realizes since the field can never change, it
will "inline" the value in the bytecode and remove the field. So imaging
public static final boolean DEBUG=true;
if(DEBUG)
{
// blah
}
When it gets compiled, the byte code looks more like
//removed field all together
if(true)
{
//blah
}
I wonder if this causes havoc with the serializers during reflection?
