The reason you get some numbers next to file names of JDeveloper (or IPs on project names) is because subversioning is enable in your JDeveloper’s options.

To disable and continue to use your external subversioning system do as follows:

From within JDeveloper:
[text]Versioning > Configure…
Deselect “Versioning Support for Subversion…”[text]

Restart your JDeveloper and the revision numbering should go away.
