Classes found in the required bundles always
take precedence over classes contained in the local bundle. This
is also true if you require the system.bundle.

Require system.bundle question Sent by:
In https://bugs.eclipse.org/bugs/show_bug.cgi?id=463292we are trying to solve the issue that javax.annotations from the Java installation should be used if a Java 7 runtime is available. If a Java 6 runtime is used, then the javax.annotations implementation provided by the plug-in should be used.
For this we added: "Require-Bundle: system.bundle" to the MANIFEST.MF.
This seems to work. If Java 7 is used as runtime, the javax.annotations from the Java installation is exported by the plug-in. And if Java 6 is used the implementation classes from the plug-in are used.
So my question is: is it assured that the system.bundle classes always get priority (if available) over the plug-ins implementation?
Or was the observed behavior pure luck and the order of which implementation is exported is not defined by OSGi / Equinox?
Thanks for the answer. I'm not sure if I was able to describe the question well enough.
Best regards, Lars
