Local fix

• Disable the SIGFPE trap in the system. The SIGFPE is disabled by
  default. The exception occurs only when the trap is enabled.
  

Problem summary

• In order to identify whether a number is negative or positive,
  inverse of number is used when the number is 0.0 for positive or
  negative infinity as comparison of 0 with negative or postive 0
  is same. This works fine in the normal condition. However, it
  can result in the exception when SIGFPE trap is enabled in the
  system.
  

Problem conclusion

• JDK has been updated to do the bitwise comparison of the number
  against  0x8000000000000000L instead of inverse the number and
  compare for positive or negative infinity.
