  ****************************************************************
  PROBLEM SUMMARY:
  Business Object mappings in BPEL can demonstrate poor
  performance or excessive memory usage when put under load or
  when using complex mappings. To improve performance under
  these conditions, module classloader-level caching of the XSL
  templates that execute the mappings was introduced.
  

Problem conclusion

• The code was altered to better utilize caching in the
  transform service.
  
  The code fix was targeted to be included in the following fix
  packs:
  7.5.1 Fix Pack 2 (v7.5.1.2)
  8.0.1 Fix Pack 2 (v8.0.1.2)
