Local fix

• Use the JVM commandline argument "-Duser.timezone=<TZ ID>". For
  example, if user is in IST timezone, use
  "-Duser.timezone=Asia/Kolkata"
  

Problem summary

• JDK expects the time zone information to be available in the
  standard location (/usr/share/zoneinfo/). However, if the user
  has removed it for some reason like reduced foot print, it can
  result in a segmentation fault. It is not recommended to move
  the time zone information from the standard location and user
  should avoid it. However, JDK should not crash even if the
  information is not available in the standard location. Hence, a
  null check for the existence of timezone files under standard
  location (/usr/share/zoneinfo/) has been added to the JDK.
  

Problem conclusion

• The JDK has been updated to introduce a null check for the
  system time zone information before using it.
