Matt Sicker updated LOG4J2-513:
-------------------------------
Attachment: 0002-Refactor-class-loader-usage-in-LogManager.patch
0001-Fix-weird-usage-of-StatusLogger.patch
Here's what I've got so far. As I mentioned in a TODO comment, the bundle
activator part would be better implemented using a declarative service (using
the Felix annotations would be the easiest way) or blueprints. However, this is
still a significant improvement in OSGi support.
I'm completely open to better names for anything here as
LoggerContextFactoryContext seems a bit ridiculous. :)
> Use more OSGi-friendly class loading mechanisms.

> See for instance
> [here|http://njbartlett.name/2012/10/23/dreaded-thread-context-classloader.html].
> Currently, o.a.l.l.util.ProviderUtil has a findClassLoader() method that
> depends on using the thread context class loader (TCCL). Now this method may
> work in certain environments, but once you're in an OSGi environment, class
> loaders are far more modular thanks to each bundle getting its own class
> loader. The thread context class loader is oftentimes not the correct one in
> such an environment.
> I'll do more research on being compatible with OSGi without depending on
> OSGi. In the meantime, this ticket will have to do.
