Subject [jira] [Commented] (FELIX-3368) Class loading fails on shutdown because zip is unreadable
Date Thu, 01 Mar 2012 13:52:09 GMT

    [ https://issues.apache.org/jira/browse/FELIX-3368?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13220030#comment-13220030

Richard S. Hall commented on FELIX-3368:
----------------------------------------

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.

fail with NoClassDefFound errors because the classloader will be unable to load the class
from the jar.
