As I mentioned earlier in this thread, I think it has something to do
with the simple configurator bundle
(org.eclipse.equinox.simpleconfigurator_1.0.0.v20080604.jar) and how
it is used to bootstrap the loading of other bundles.
Here is the exception I get (the first line of the stack trace only).
As I said, this exception is thrown, but somehow, the bundle is still
able to be loaded.
org.osgi.framework.BundleException: The bundle could not be resolved.
Reason: Missing Constraint: Require-Bundle: org.aspectj.weaver;
What happens is this (I think):
1. there is an attempt to start the weaving service at level 1
2. but this requires starting org.aspectj.weaver and org.aspectj.runtime
3. since these two bundles are not specified in the config.ini, but
rather the org.eclipse.equinox.simpleconfigurator/bundles.info file,
these two bundles cannot be located until the simple configurator
bundle is completely started. (so an exception is thrown)
4. Once the simple configurator bundle is started, the aspectj weaver
and runtime can now be found and the weaving service can finally be
(note- this is only a conjecture based on what I know about equinox (not much))
Does this make any sense?
