64-bit windows is supported in Beta2.Our system running on RHAS requires use of 64 bit JVM, so unless there is a way to load 32 bit shared objects into a 64 bit process, we can't use this long-awaited API in its current form. It seems others are in the same boat. Can you please (pretty please?) provide a 64 bit version for Linux?
We have no plans for 64-bin Linux.
