IV34355: THE IO CONVERTER FOR IBM1047_LF,IBM1141_LF AND IBM924_LF CODEPA GES GIVE INCORRECT MAPPING FOR LINE FEED

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  The IO converter for  IBM1047_LF,IBM1141_LF and IBM924_LF code
  pages should give the  swapped value of  line feed compared to
  IBM1047, IBM1141 and IBM924 code pages. However, those code
  pages is giving the same value of line feed as  IBM1047, IBM1141
  and IBM924 code pages.
  The correct mapping of   IBM1047_LF,IBM1141_LF and IBM924_LF is
  as follows:
  \u000A <-> 0x25
  \u0085 <-> 0x15
  The NIO converter for  IBM1047_LF,IBM1141_LF and IBM924_LF code
  pages are working correctly.
  

Local fix

• The issue can be be work around using the following options:
  1. Use NIO converter instead of the IO converter. This work
  around is possible if explicitly specifying the codepage in the
  application.
  2. Use the system property  -Dibm.swapLF=true with code pages
  IBM1047, IBM1141 and IBM924  . The property is system wide and
  cannot be selectively apply to any specific code page.
  

Problem summary

• The IBM1047_LF,IBM1141_LF and IBM924_LF code pages did not
  override the charmap array in byte to char conversion and
  thereby use the mapping of parent class
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR13
  6.0.1 SR5
  7.0.0 SR4
  .
  JVM has been updated to  override the charmap array to get the
  correct  mapping in  IBM1047_LF,IBM1141_LF and IBM924_LF code
  pages.
