I'm working on upgrading ServiceMix to Karaf right now. The work is done in a ServiceMix sandbox [1].
The issue you hit is a known issue (at least from me). The very reason is that OSGi has this concept of package which can not be easily split. If you look at the javax.transaction package in the JVM, you'll see it only includes a few classes, not the full JTA spec as specified by JEE. This means that if the system bundle exports this package, everything will be wired to that one instead of the one from the geronimo jta spec. There are multiple solutions to this problem, but the easiest one is to make sure that the system bundle does not export those packages. That's what i've done at [2] where you can see that the javax.transaction packages are commented, thus not exported. Hopes this help!
