I logged a ticket https://issues.apache.org/jira/browse/KARAF-2105 Freeman or Jean if any of you got free cycles. Then it would be great to work on this. And get a SNAPSHOT .tar ball of karaf 2.3.x. Then I can help give that a test drive with the Camel 2.11 SNAPSHOT, to see if its fixed. > Thanks > －－－－－－－－－－－－－ > Freeman(Yue) Fang > > Red Hat, Inc. > FuseSource is now part of Red Hat > Web: http://fusesource.com | http://www.redhat.com/ > Twitter: freemanfang > Blog: http://freemanfang.blogspot.com > http://blog.sina.com.cn/u/1473905042 > weibo: @Freeman小屋 > > On 2013-1-5, at 下午7:11, Claus Ibsen wrote: > >> Hi >> >> In the Apache Karaf 2.3.0 distribution, there is a standard features >> file which has a number of spring features. >> >> Take a look in this file: >> http://repo2.maven.org/maven2/org/apache/karaf/assemblies/features/standard/2.3.0/standard-2.3.0-features.xml >> >> Notice that there is 3 different spring versions supported >> - 2.5.6 >> - 3.0 >> - 3.1 >> >> The first two (2.5.6 and 3.0) have the same name "spring" but differs >> in the version attribute. >> And only Spring 3.1 has its own feature name "spring31". >> >> This is a very unfortunately problem, as it makes it much header to >> re-use the Karaf features for >> referring to Spring. >> >> So for example in Apache Camel we do that.
