JVM crashes with SIGBUS signal on opening DB from Java code

[zjshen]

Hi Leveldb JNI folks,

Recently we encountered one JVM crash issue when using leveldbjni 1.8. Bellow is some information from hs_err_pid.log. According to the log, it seems that JVM crashed when the app tried to open DB files.

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGBUS (0x7) at pc=0x00007f3512b19990, pid=6732, tid=139865935472384

# JRE version: Java(TM) SE Runtime Environment (7.0_67-b01) (build 1.7.0_67-b01)
# Java VM: Java HotSpot(TM) 64-Bit Server VM (24.65-b04 mixed mode linux-amd64 compressed oops)
# Problematic frame:

Do you have any idea what could be the cause of JVM crash? It's appreciated if you could share your opinions.

Thanks,
