Hi Angelo,
I am confused. Please help me understand something here. If what you
said were the intention of the spec, why does the spec require
Bundle.loadClass() to cause the corresponding bundle to go to ACTIVE
state when the bundle uses LAZY activation policy [1]? Seems like LAZY
is more eager than EAGER activation policy (the default policy)!
Thanks for your prompt response,
Sahoo

Hello Sahoo,
The thing you're seeing is exactly what it should do. The RESOLVED
state means that, on the module layer, all the bundle's imports are
available (the manifest's ImportPackage: statements), and its exports
are done too. Now, any bundle that imports packages which are exported
by your test-bundle, can load classes from those packages.
In short, the RESOLVED state handles the package wiring, only in the
ACTIVE state all services are registered, but that has nothing to do
with the ability to load classes.
Hope that helps,
Angelo

Hi,
I am observing a strange thing. I see a bundle in RESOLVED state even
after a class has been successfully loaded from that bundle. How is
this possible? I am explicitly starting the bundle from another
bundle and loading a class using Bundle.loadClass. Based on the
following output (with annotations), I have concluded that the class
has indeed been loaded by the bundle in question.
