  N/A
  

Local fix

• N/A
  

Problem summary

• The  IShellFolder obtained while creating  the ColumnComparator
  can be invalid while doing the actual compare operation with
  ColumnComparator and can result in  crash.
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR4
  .
  The JVM has been updated to obtain the IShellFolder value
  dynamically at the time of compare operation and there by ensure
  it is valid and avoid the crash.
