[jira] [Created] (FELIX-3368) Class loading fails on shutdown
because zip is unreadable
Class loading fails on shutdown because zip is unreadable
---------------------------------------------------------
Key: FELIX-3368
URL: https://issues.apache.org/jira/browse/FELIX-3368
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: framework-3.2.2
Reporter: Dustin Schultz
If a particular module executes a shutdown hook which loads a class at runtime, it will fail with NoClassDefFound errors because the classloader will be unable to load the class from the jar.
ERROR: JarContent: Unable to read bytes. (java.lang.IllegalStateException: zip file closed)

-----------------------------------------------------------------
Yes, that is correct. You cannot load classes from a bundle after the framework shuts down. This bug really duplicates FELIX-2128, so you should check the discussion there. However, I'm still inclined to treat this as a "WON'T FIX".

------------------------------------------
Couldn't we just throw ClassNotFoundException in this case ? (or maybe I am just off by a bit ;-) )

----------------------------------------
When this topic came up before, I think I looked into changing the exception, but it didn't seem easy to do at the time, since the error happens pretty deep down. Feel free to take a look.
