CXF installs a BouncyCastle provider globally into the security providers list. This is causes performance and other problems when this provider gets chosen for whatever reason to be the system crypto provider for e.g. TLS.

The list of globally installed security providers should be a user concern only. If CXF requires a specific provider for a specific purpose, it should be selecting that provider when constructing the crytpo API object, though generally this is to be discouraged.

Ultimately we want to introduce a configuration in the app server that allows the list of security providers to be specified in some way, without interference from any frameworks that we happen to have installed.
