> When a bundle is undeployed when ServiceMix is stopped, on the next restart the FelixStartLevel
thread enters an infinite loop.

> This is a side-effect of change FELIX-2942, in which the "for" loop has been replaced
by a "while" loop on a boolean "bundlesRemaining".  The "bundlesRemaining" is not recomputed
in every iteration the loop. For instance, when a IllegalStateException is caught, it skips
to the next iteration of the loop ("continue").  It therefore loops infinitely.
> Suggestion solution : recompute the boolean "bundlesRemaining" at each iteration of the
loop (perhaps in a "finally" block ?).
> This regression has been introduced in Felix 3.2.x : version 3.0.x did not have this
problem.
> The impact on ServiceMix users is that "cold undeploy" is broken, but fortunately, "warm
undeploy" is not.
