Hi, In fact the inconsistency was the following:
Bundle A: Export-Package: org.foo (Class A) Bundle B: Export-Package: org.foo (Class A) Bundle C: Import-Package: org.foo Bundles A and B exports the same package that contains the same class. When i was testing i saw that the order of installation affected me, but in OSGI the order doesn't have to affect. So this confused me until i found the problem.
