Subject: Allow JioEndpoint to switch context class loader
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=2d24d1c1d3973bdc5348b4e12c87b947e3b8526d;p=tomcat7.0

Allow JioEndpoint to switch context class loader
under security manager. Code copied from standard session.

Add two more classes to class pre-loading to improve
security manager interoperability.
