DIIOP TrustedCerts.class regenerated?

Is there a reference that will tell me under which exact conditions the TrustedCerts.class file will be regenerated by DIIOP on the Domino server? We have a few external java programs pulling information from Notes databases over SSL. We must have the TrustedCerts.class file on the classpath of these java apps for this to work. We know if Domino is upgraded, we’ll need a new copy of the class file. But, recently our Domino server crashed and the class file was regenerated. It is a very tedious process to get the new class file, recreate a new jar with it, check that into our Maven repository with a new version number, rebuild the java applications and redeploy them every time the file changes.

Thanks!
