Version numbers in the OTDT follow this schema:
The newest OTDT is build on top of the newest 3.6 milestone release of Eclipse ("Helios")
1.4.0 Milestone x
For the OTDT this is the x th milestone release within the 1.4 stream.
The adapted JDT core plug-in contained in the OTDT is tagged with a version number where the first three parts match that version of the original JDT core from which the OTDT is derived (here "3.6.0"), while the version qualifier contains a condensed form of the OTDT version (here "r140"). This ensures that the framework accepts the OT-version of the JDT core as an upgrade over the original.
