  ****************************************************************
  After the application was installed and uninstalled, its
  registered types were not freed up from the SDO type registry.
  

Problem conclusion

• The SPI ReferenceSharingScopeManager used by WebSphere Proces
  Server keeps the object reference to the uninstalled types so
  the JVM cannot garbage collect them causing the memory leak.
  The memory leak has been corrected.
  
  APAR PM11718 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
