We are in process of migrating spring based camel application to blue print based camel application. We are also migrating to fuse 6.1 version. I am using Pax Exam with Junit runner along with apache felix container to perform of my unit testing. I am facing problem on unresolved bundle problem related to ehcache manager. I have tried giving required depencies to pax configuration as mavenBundle but without anyluck. Exception doesn't give detail about missing dependencies instead it gives generic error of package only i.e., "osgi.wiring.package=net.sf.ehcache".
I have given necessary depencies in pom.xnl and eclipse doesn't show any error. Below is configuration used in Junit.
'@Configuration public Option[] config() {
return options(systemProperty("org.ops4j.pax.logging.DefaultServiceLog.level").value("DEBUG"),
systemProperty("Test.Property").value("system"),
systemProperty("pax.exam.logging").value("none"),
systemTimeout(600000),

I have managed to resolve the problem by upgrading the ehcache version to latest of 2.8.5. ehcache-core expects higher version than one I am using as 1.5.2 version of ehcache.
For osgi beginners like me, the bigger problem is not getting right error message which leaves me to spend lot of time to do investigation.
