Local fix

• NA
  

Problem summary

• This problem is specific to z/OS platform.
  When an unsupported encoding is used, its expected to fall back
  to the default encoding of the platform.
  When "export LC_ALL=Ar_AA.IBM-425" is set, both file.encoding
  property and ibm.system.encoding property get set as "IBM-425".
  Fallback mechanism implementation sets only the file.encoding to
  Cp1047. ibm.system.encoding still points to 'IBM-425'.
  Hence the failure is noticed.
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR6 (z/OS 31-bit)
  7.0.0 SR6 (z/OS 64-bit)
  .
  In the fix, we are trying to over come the problem bypassing the
  java.nio.charset.UnsupportedCharsetException exception.
  

Temporary fix
