Hi
I already read about VM kit in this paper [1], but its more focused in
security for a JVM and they do heavy modification in the VM. I think i
can resolve my problem with Felix modifications and a bit of JVM TI[2]
using. For what i have understand of the code i think its possible to do
what i wa

No,
VMKit is a very interresting project. Thanks.

On Sat,
Hello João,
After reading what you're trying to do, I immediately had to think
about some research I learned about when attending FOSDEM'09 recently.
It's called VMKit, and based on it, they are doing research into using
a new isolation abstraction for OSGi.

My tip is essentially to just try to start your thread before the
calling thread gets the locks in question.
If that is not possible, you will have to look at which locks it
acquires. If they are part of the locking protocol implemented by Felix,
then you might be able to modify them to make t
Hi
Yes Im using trunk code. I got this idea from this previous work [1] but
unfortunately the code is not available.
Im not sure i understand your tips, because im not very familiar with
the code and what the start level is supposed to do.
What i need is that the start() method of the bundle is
I am not sure what you want to do is possible.
At a minimum, you would have to do your hand off before the start level
thread acquires the locks. If the start level thread is only acquiring
lock objects, you could potentially modify them to make them
transferable to another thread, but this wo
Hi
I'm doing some work in OSGi in an attempt to add better resource
monitoring to osgi applications. My objective is to isolate the cpu
consumption across the different bundles. To implement this my strategy
is to group the different threads in ThreadGroups, where there is a
different ThreadG
