Sorry for the late reply, too many things going on. I have a few comments:

1. I agree it's good to check the output in addition to checking for a 
non-0 exit. However it turns out to be fragile: it might be "in both 
module m1 and m2" on one system and "in both module m2 and m1" on 
another. This is because the system module path varies by platform and 
build configuration.

2. testOverlapUpgradePath assumes that the upgrade module path can be 
used as an alternative to the application module path. There are several 
discussion points around the upgrade module path but I don't expect it 
can be used to do anything other than upgrade modules that are on the 
system module path (or linked into the runtime image). So maybe this one 
should be dropped for now.

3. The @summary in OverlappingPackagesTest should be used as the updated 
test includes positive scenarios now.

4. I'm sure that that OverlappingExportedPackagesTest is the best name 
for this test because it is testing several negative scenarios that are 
specified by Configuration.resolve. I think we've already got each of 
these cases covered in ConfigurationTest but good to have them tested at 
startup for the boot layer too.

5. There are trailing spaces and tabs in the patch.
