new update for java se embedded 8 and i tested with my n900 cssu stable and it work but last thing while installing is to use this ln -s /opt/java/ejre1.8.0/linux_arm_vfp_sflt/jre/bin/* /usr/bin/ Not ln -s /opt/java/ejre1.7.0_45/bin/* /usr/bin/

edit: better to stay version 7 Update 51 because some of the my apps doesn't work with 1.8.0 and work with 1.7.51
