Summary
-------
Remove the RSA support in SunJSSE provider which are duplicates of SunRsaSign provider.

Problem
-------
For historical reasons, SunJSSE provider contains support for RSA algorithms, i.e. KeyFactory, KeyPairGenerator, Signatures. Starting JDK 5, SunRsaSign provider is introduced for supporting these and more RSA algorithms. The only reason for SunJSSE provider to continue supporting these RSA algorithms are for pre-JDK5 applications. It's time to clean up and remove this duplicated support for RSA algorithms from SunJSSE provider.

Solution
--------
Remove these RSA entries from SunJSSE provider service registration.
