Hello,
I'm using a bundle that requires
(package=javax.annotation)(version>=1.1.0)(!(version>=2.0.0)).
Unfortunately the version exposed by the system bundle on my system is only
0.0.0.1_007_JavaSE.
I have a bundle that exposes the requested package at a matching version
(mvn:javax.annotation/javax.annotation-api/1.2-b04) however when I add this
bundle I get errors like the following:
[java] ERROR: Bundle org.glassfish.jersey.core.jersey-common [44]: Error
starting
slinginstall:C:\Users\Reto\projects\apache\commons-ng\launchers\mini\target\stanbol\startup\24\jersey-common-2.0.jar
(org.osgi.framework.BundleException: Constraint violation for package
'javax.annotation' when resolving module 44.0 between existing import
35.0.javax.annotation BLAMED ON [[44.0] package;
(&(package=javax.annotation)(version>=1.1.0)(!(version>=2.0.0)))] and uses
constraint 0.javax.annotation BLAMED ON [[44.0] package; (&(package=
com.google.common.net)(version>=14.0.0)(!(version>=15.0.0))), [9.0]

Can I prevent the system bundle from exportingthis package?
Yes, you can. You have to completely overwrite the
org.osgi.framework.system.packages property. The default value comes
from the default.properties file inside the felix.jar file. You can copy
copy the value to your conf/config.properties. Note that it uses
property expansion in default.properties, so you'll have to expand the
properties by hand.
Or is there an other solutions?
Not really. It looks like you have one bundle using the correct imported
version range and one not and unfortunately the system bundle export has
priority in a lot of cases since it is resolved first. The only other
approach is to make sure the higher version of javax.annotation is
resolved before resolving any other bundles, so that it will become the
highest priority since it has the highest version.
But I think modifying the system bundle export is the all around safer
way to go.
