Hi everybody,
As the subject of this thread tries to states, my question is regarding
objects created through an embedded framework and how safe is to use
them after the bundle providing their classes is updated or uninstalled.
I'm trying to replace part of an application with OSGi by means of an
embedded framework. The idea is that OSGi will empower the application
with multiple class versions handling.
Then the application will create objects from classes provided by
different bundles and use them through a common interface (shared
between the application and the embedded framework).
What I want to know is if there is any danger and what (mis)behavior
should I expect if/when a bundle providing some classes is uninstalled
or updated (and refreshed).
I know that the objects will retain their reference to the classes (and
classloader), and thus, I would expect there is no problem. But since
I'm not an expert neither in OSGi nor Java, I wanted to get some insight
from you (the expert ones).
I've read a previous thread about objects and unisntalled services that
created them [1] that (I think) confirms what I suspect. However, the
thread continues with a discussion about how the invalidation of those
objects should be enforced, and I want to know why my objects should be
invalidated and what are the dangers of not doing so.
Hope I've been clear enough about my doubt.
Thank you in advance for any comment about this.
Kind regards
