In jre.properties it is assumed that jre-1.7 supports javax.annotation;version="1.2", but this seems to be incorrect. Deploying bundles that depend on javax.annotation-1.2 specific behavior will fail. We should downgrade the version to 1.1.
If any bundle needs javax.annotation-1.2 someone should install javax.annotation/javax.annotation-api/1.2 wiith a start level less than 5 (system bundles start at 5 by default).
