Well, not certain about why (may be the armel EABI), but trying to run "java" from a command prompt results in the error "/bin/sh: ./java: not found". This occurs even if the $PATH is set properly.

"file java" on the executable results in "bin/java: ELF 32-bit LSB executable, ARM, version 1 (ARM), for GNU/Linux 2.4.3, dynamically linked (uses shared libs), stripped"

Short version, looks like it won't run, but the Release Notes file says that Sun's engineers can provide custom builds - anyone want to request one?
