RFR: 8158111: Make handling of 3rd party providers more stable

[Ivan Gerasimov]

Hello!

In the file
src/java.base/share/classes/sun/security/ssl/RSAClientKeyExchange.java:

When doing the debug printing:
                     System.out.println("The Cipher provider " +
                         cipher.getProvider().getName() +
                         " caused exception: " + iue.getMessage());

cipher.getProvider() may throw an exception, which will cause the 
fail-over branch get skipped.


Furthermore, in the fail-over branch it is better to re-acquire an 
instance of the cipher, as the previous call to init() might have left 
the current instance in inconsistent state.

Would you please help review the proposed fix?
