I have installed following required libraries
apt-get install make build-essential lib32ncurses6 libc6-i386
Is there anything else which needs to be installed ? Firewall setting seems to be fine. As per to logs the exception happens in
# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00007f5ae8aedfd2, pid=97585, tid=0x00007f5b0fbca700

do you have any visibility on what might have caused this ?
