The defects fixed in CIM 6.0.0 HF 4 are:

1-85CNGS

On WebSphere, CIM may display the following Null Pointer exceptions:

- JAV-8001 "NullPointer" Exception under heavy load.

- GEN-7001 "NullPointer" Exception when record caching is enabled.
  The Null Pointer exception may occur under heavy concurrent load
  conditions or when the GUI is used along with import of 500 or
  more items. Record caching must be disabled to avoid any unexpected
  results.

  Record caching is enabled by default. To disable the caching of
  records, set the tibco.optimization.cache.record property in the
  MqProperties.confg file to false. If this property is already
  present, make sure it is set to false.
