Won't this potentially cause problems out in the wild?
com.google.inject is not a singleton, and if were to have both
versions of the plugin in your system a require bundle would pick up
the correct one ... an import package would always pick the version
exporting 2.0 packages (IIRC).  Perhaps not a bother since the
difference is the package versioning, but what about if the next
version of com.google.inject exports packages 1.3 ... as long as that
2.0 bundle version is in the system, it will be chosen over 1.3.

I thought this cause a problem when org.junit4 was exporting hamcrest
library packages at 4.5 (but really they were 1.0) and a consumer
wanted to use the hamcrest plugins which were exporting packages at
1.1.  We had to fix that before we shipped.

If I've misread what the problem was, I apologize for the question.

Later,
