  With performance evaluation, it was discovered that DataHelper
  and checking xsi:type attribute implementation can be improved
  to reduce memory footprint.
  

Problem conclusion

• DataHelper implementation has been improved to avoid
  unnecessary data format conversion. Also, NodeTest object will
  be cached and reused for checking the xsi:type attribute
  instead of creating the object every time.
  
  APAR PM09687 is currently targeted for inclusion in Service
  Level (Fix Pack) 1.0.1.3 of WebSphere Application Server v7
  Feature Pack for Service Component Architecture (SCA) Refresh
  Pack. Please refer to the Recommended Updates page for
