Unable to start Cassandra Daemon 1.2.4 with Java 8 -

hi using cassandra 1.2.4 java 8(moving on 7) service .i can run cassandra standalone process without hassle, when use apache virgo application(3.7.0.d-20150114193621) fails. following output in status.out log file , nothing in system.log.

+ case "$1" in + echo 'checking status of cassandra daemon......' checking status of cassandra daemon...... + is_running ++ get_cass_pid +++ ps -fc java +++ grep -w org.apache.cassandra.service.cassandradaemon +++ head -n 1 +++ awk '{print $2}' ++ echo + pid= + '[' x = x ']' + return 1 + stat=1 + case "$stat" in + echo 'cassandra not running' cassandra not running + exit 1 

i below stacktrace in virgo logs:

error     taskexec-1-thread-8      de0005i failed start cassandra service 

since, can run fine standalone process, there no issue setting $cassandra_home,$classpath or other variables. have verified api call application , looks not able start daemon. also,any information relating cassandra logging helpful debug.
