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.
