  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
