Important bugfix release; strongly recommended to upgrade to this version.
Fixes issues where classloaders can't always find classes listed in the classpath, by ensuring that each classloader is used to load classes found within its classpath elements, rather than relying on the system classloader to do the right thing. (#37)
Bumped the version number from 2.0.x to 2.2.x, because this breaks the API of ClassLoaderHandler. The vast majority of users will not be affected by this change.
Also includes the important bugfixes and performance improvements released in the last few 2.0.x versions.
