Many warnings from InMemoryDAO while reading DIP data

[GoogleCodeExporter]

When parsing DIP db (human only, PSI-MI 2.5, 
ftp://dip.doe-mbi.ucla.edu/2014/mif25/Hsapi20140117.mif25.gz) 
I am getting hundreds of warnings from 
psidev.psi.mi.xml.dao.inMemory.InMemoryDAO class
(mostly about ExperimentDescription or Participant, and id - either 0, 1, or 
2....):

2014-03-24 12:53:06,308 WARN  p.p.m.x.d.i.InMemoryDAO - Attempt to overwrite an 
existing ExperimentDescription with id: 0

Are these norm, i.e., the parser successfully recovers from those errors; can 
we depend on the data/model after it's read or something to be fixed?
