  Customer informed that he runs a test program which attempts to
  validate the encoding and decoding characters present in all
  installed encodings in JDK 6. He reported that test program
  fails to run on following converters:
  IBM01140
  IBM01141
  IBM01142
  IBM01143
  IBM01144
  IBM01145
  IBM01146
  IBM01147
  IBM01148
  IBM01149
  IBM1141_LF
  x-EUC_CN
  x-EUC_TW
  x-IBM1041
  x-IBM1088
  x-IBM833
  x-IBM942
  

Local fix

Problem summary

• The problem is caused due to incorrect mappings present in JDK
  converter tables for following code pages:
  IBM01140
  IBM01141
  IBM01142
  IBM01143
  IBM01144
  IBM01145
  IBM01146
  IBM01147
  IBM01148
  IBM01149
  IBM1141_LF
  x-EUC_CN
  x-EUC_TW
  x-IBM1041
  x-IBM1088
  x-IBM833
  x-IBM942
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR10
  7.0.0 SR1
  .
  JVM has been fixed to avoid charsets reporting Unmappable char
  and Malformed char error messages. Also fixed encoding &
  decoding errors for reported code pages.
  .
  To obtain the fix:
  Install build 20111028 or later
  

Temporary fix
