 This method traverses the list of registered security Providers, starting with the most preferred Provider. A new TrustManagerFactory object encapsulating the TrustManagerFactorySpi implementation from the first Provider that supports the specified algorithm is returned.

 the Security.getProviders() method.

 In some cases, initialization parameters other than a keystore
 may be needed by a provider.  Users of that particular provider
 are expected to pass an implementation of the appropriate
 ManagerFactoryParameters as defined by the
 provider.  The provider can then call the specified methods in
 the ManagerFactoryParameters implementation to obtain the
 needed information.
