Oh yes, I meant the i386 cross-tool *you* provided on x86_64 .
BTW, there are a bunch of ready-made cross tool rpm's on
linked from wine's dev-guide:

I do use Java, just not in relation to R - it has been a while since
I played with SJava. Sun's JDK (32-bit) has been working consistently.
On FC5 x86_64 the default
gcj-based JRE was a bit funny, but since upgraded to FC6, I found
the gcj-based JRE on x86_64 can run haploview
(http://www.broad.mit.edu/mpg/haploview/) reasonably well.
If you want 64-bit R working with a 64-bit JRE, the gcj-based jre seems
to be the only route. I have built something involving JNI recently
using the gcj-based jdk seems alright. (it did finish compilation
- it is a suite of applications [http://gridengine.sunsource.net/],
only a small part is JNI based and I don't know the specific
part well enough to judge for an mis-compilation or
