Local fix

• No known workaround exists.
  

Problem summary

• A javacore cannot be processed by jdmpview or other tools that
  use the DTFJ API when one or more registers recorded has a value
  that requires more 64 bits.
  

Problem conclusion

• The code in DTFJ has been updated to properly handle wide
  values.
  .
  This APAR will be fixed in the following Java Releases:
     8    SR5 FP25  (8.0.5.25)
  .
