Local fix

Problem summary

• With these encodings, during the JVM load time initiliazation of
  encoding specific classes happens and they were trying to get
  the system architechture property value which is not available
  by that time in the system property table and the value returned
  is NULL. When this value is compared against the known
  architechture names using String.equals(), this throws NPE as
  the string used to compare is a NULL string
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR1
  .
  Architechture property will be available in the system property
  table when the JVM is completely loaded. So this property value
  is queried only after the JVM is loaded completely
