Mark Struberg commented on DELTASPIKE-782:
------------------------------------------
The only thing which is wrong is that some containers try to bootstrap
applications with a totally different ClassLoader than they use later at
runtime. That CRIES for problems! And we are just the first one to blow up, but
there are many more issues with that approach (again: not OUR approach, but the
container setup).
You MUST support the case that someone stores classes, static fields etc when
booting up and using CDI extensions. If you later at runtime would use another
ClassLoader, then all those instances collected in some CDI extensions (not
only DeltaSpike!) would crash with ClassLoader errors.
There are basically 1 valid scenarios:
1.) The container boots up with the 'EAR ClassLoader' and later uses different
child classloaders for each WAR at runtime. Still the WarClassLoaders have the
EarClassLoader as parent -> works perfectly fine with DS.
2.) Each WAR get's booted with it's own BeanManager (+ 1 for the 'common' parts
like JMS). This is what you get in WebSphere. -> works perfectly fine with DS.
3.) There is only 1 ClassLoader and all is treated as 'flat' -> works perfectly
fine with DS.
So what is the issue? Where can I retest the scenario to see what the real
problem is?
