John Ross commented on ARIES-931:
---------------------------------
Are there any objections to my releasing the contents of aries931.patch? To
summarize, the patch will have Applications iTests run against Equinox 3.8 for
the Aries build in order to avoid a recurrence of the NPE/CME. The ability to
run against 3.5 and 3.7 remains but would need to be enabled and run locally if
necessary.

> The CME is a known issue and was fixed as of Equinox 3.7.2. Currently, the
> application-itests run against both Equinox 3.5.0 and 3.7.0, which are
> subject to the CME. Unless running against these frameworks is absolutely
> necessary, I'd like to propose that the itests be executed against 3.8,
> available in Maven Central, instead in order to avoid these potential "false
> positives" in the Aries build test results. The other configurations can
> remain in order to run locally when necessary but would be commented out.
