    N/A
    

Local fix

  • N?A
    

Problem summary

  • JVM fails to load with ISO8859-15 encoding
    

Problem conclusion

  • This defect will be fixed in:
    5.0.0 SR11
    .
    We are requesting the os.arch property before the JVM is
    completely loaded and in such case we are ending up in NPE as
    the returned value is NULL for this property.Since the crash is
    observed on Z platforms and the alignment has any way set to
    false for Z architecture, we can directly set unaligned to false
    and have the os.arch request block of code is enclosed with in a
    condition that evaluates only when JVM is completely loaded.
    .
    To obtain the fix:
    Install build 20090918 or later
    

Temporary fix
