Red Hat Issue Tracker WFLY-3422 0 Major Closed VFSResourceLoader is creating too many code sources 2014-07-02 01:29:45 UTC

Description David M. Lloyd 2014-05-30 16:05:54 UTC 
Description of problem:

The VFS resource loader creates a new code source object for every class in a class loader, even though they can (and should) be shared among all classes with the same signers.  This wastes a small amount (generally 1kB or less) of memory for every non-static-module class that is loaded.
