Hi,
Let's say SerivceA is in BundleA, ClassB is in BundleB
This problem could be caused by BundleA start before BundleB, so the
static Class B not get initialized at all when BundleA starting, this
is a timing issue and your logic depend on bundles start sequence
isn't a good practice in OSGi world.
How you reference ClassB in ServiceA? If you expose object in ClassB
as an OSGi service and reference it in ServiceA, then BundleB will
always get initialized firstly so you won't see this timing issue.

I have a service A instantiated by blueprint. The constructor of
service A
has reference to a static object in Class B in a different bundle.
Blueprint kept on giving me java.lang.NoClassDefFoundError and
java.lang.ClassNotFoundException on Class B.
This seems to happen only on the first startup but resolves itself
if I
restart Karaf. It probably have to do with the fact that I prepare
all the
bundles in the deploy directory without defining any feature.
I am running out of idea how to debug this issue. Your help would be
greatly appreciated.
