We are trying to install an Eclipse feature that we developed into the RTC 6.0.6 Eclipse client on Mac OS X-64.

The installation fails with the following error:

Cannot complete the install because one or more required items could not be found.
Software being installed: MyFeature Client Feature 1.2.3.101808282330

The RTC Eclipse client was downloaded from
https://jazz.net/downloads/rational-team-concert/releases/6.0.6/RTC-Client-Mac64-6.0.6.zip.

The same Eclipse feature installs just fine into the RTC 6.0.4 Eclipse client for Mac OS X-64 and
under RTC 6.0.6 Eclipse clients on Linux and Windows.
The Linux and Windows RTC 6.0.6 Eclipse client that work are using the bundled Java.
I also tried running the RTC 6.0.6 Eclipse client on macOS under different Java 7 and Java 8 version in addition to the bundled Java.

Question:
Why the RTC 6.0.6 zip version for MacOS is different from the the ones for Linux and Windows ?
