Here's the call stack of the most expensive path, in case it helps:


XmiCasSerializer$XmiCasDocSerializer.<many places>
CASImpl.ll_getTypeClass(int)
TypeSystemImpl.subsumes(int, int)
TypeSystemImpl.ll_subsumes(int, int)
TypeSystemImpl.ll_isArrayType(int)
TypeSystemImpl.ll_isValidTypeCode(int)
SymbolTable.getSymbol(int)
Vector.get(int)
