Q regarding ExecutionEnviroment
Hi,
I have a question regarding ExecutionEnviroments supported by Felix
framework.
Q. Can it run on CDC Foundation Profile 1.1 ?
Thank you in advance,

So, if there is only one framework running on the system, (it is usual
in the embedded world, the feature does not mean anything.

File locking will be enabled by default, you will need to disable it on
Foundation. Yes, the feature will be missed. However, we survived 10
years without it, so I doubt it will be missed. :-)

Nothing. Just don't configure two frameworks to use the same bundle cache.

> (Do you have any timeline ?)
Next micro release. Hopefully in a week or two. Use 3.0.5 for the time
being...or comment out the feature and build your own snapshot from trunk.

Q1. Is my understanding correct ?
- After introducing the configuration property, the Felix framework will
be able to run on CDC FP1.1. However, in that case, "cache locking"
feature will be missed.
Q2. Could you tell me about "cache locking" feature ?
(What will be a problem in CDC FP1.1 case?)
Q3. When will the configuration property be introduced ?
(Do you have any timeline ?)

We don't test on it regularly, but we try to not use recent Java
features, so it should and if not, you can report issues. Currently,
there is this outstanding issue:

This was the result of a recent change, so we'll introduce a
