I've gone ahead and change back to the previous state.
I've made one change though which is to have the bundle export and
import the javax.transaction.* packages.
This should allow both ways to work, i.e.
   * have your system bundle exporting the javax.transaction package
with version 1.1 and have jta api in the system classpath
   * boot delegate javax.transaction.* package and add a mandatory
attribute on those pacakges exported by the jre
