Sahoo created FELIX-3713:
----------------------------

             Summary: Bundle.start() returns without starting the bundle
                 Key: FELIX-3713
                 URL: https://issues.apache.org/jira/browse/FELIX-3713
             Project: Felix
          Issue Type: Bug
          Components: Framework
    Affects Versions: framework-4.0.2
            Reporter: Sahoo


See email exchange between Sahoo & Richard that happened in dev alias on 16th Oct 2012
for issue details:

> While investigating some issues in GlassFish, what we are seeing is that even if our
code is calling bundle.start(START_TRANSIENT), the bundle is not getting started immediately,
nor is the code blocking. It simply returns without Bundle's activator getting called and
bundle.getState() == RESOLVED. We see this happening when there is a start level change in
progress. We are currently using Felix 4.0.2. Looking at the code, I see this to be by design,
but isn't it a non-compliant behavior? Should bundle.start() not wait until the bundle is
started?

The spec has always been a little lenient about how start levels are processed to give leeway
to the frameworks. For us, we viewed this as somewhat of a race condition between threads
starting bundles and the start level thread.

However, in the transient case, I wouldn't expect it to remain in RESOLVED state. If its start
level wasn't met, it should have thrown an exception. Yet there is a chance in the transient
case that it could start asynchronously...not sure if this would really be problematic for
you or not...

But it shouldn't remain in the RESOLVED state. Looking at the code, I think there is a bug
in this scenario where a transient bundle that is handled asynchronously will not actually
end up getting started since the start level thread checks the persistent state of the bundle,
which is not set for transient bundles.

You could definitely open up a bug for this last issue...
