ERROR DESCRIPTION:                                              
During application startup time, the SCA runtime attempts to    
load all WSDL interfaces into memory, whether are not these are 
actually referenced by the various artifacts in the application.
This sometime leads to a memory leak and an eventual            
OutOfMemoryException. This problem is similar to that described 
in botp internal defects 405769, 405769.2 and 431231.
