I was thinking of writing some JNI to access the Windows file
attributes. On the Java side this would be an EnumSet. On the Windows
side it would be a bitmap. Are there are any fast ways to
interconvert?

Fast, as in optimal, or Fast as in, takes less than 5 minutes to
create?
I don't know much about JNI, but I think my approach would be have
this method be private, and simply return the bitmap value (in a int
value, or is possible, a BitSet). Then convert it to a BitSet. Have
the enums declared in the order that the BitSet reports the bits, and
use bitSet.nextSet() (I think thats the name) to determine the ordinal
of the enum you want to add to the EnumSet.
So, in other words, the conversion would be done on the Java side, and
you don't need to worry about performance until you find it to be a
bottleneck.
