JDK-6760316 - JVM crashes on systems without swapping and no space left in temp dir
Description
JVM crashes with SIGBUS on systems without swapping and when no space is left in temp dir (/tmp for example).

JVM should handle the case when /tmp is full more gracefully and/or report a reasonable error rather than crashing.

1. Fill temporary directory (xxxM):
# cd /tmp
# dd if=/dev/zero of=filexxxM.tmp bs=xxxM count=1


2. Run Java (crashes): 
# java -version

#
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGBUS (0x7) at pc=0x00002ba4c02743cb, pid=32329, tid=1088387392
#
# JRE version: 6.0_17-b04
# Java VM: Java HotSpot(TM) 64-Bit Server VM (14.3-b01 mixed mode linux-amd64 )
# Problematic frame:
# C  [libc.so.6+0x7b3cb]  memset+0xa5b
#
# An error report file with more information is saved as:
# /tmp/hs_err_pid32329.log

PUBLIC COMMENTS As another aspect of this RFE, there should be documentation stating that one should use the proposed workaround options with critical/HA Java processes in Linux.
