> Reason : IBM websphere uses its own jre and supports only IbmX509 keymanager algorithm which is causing an exception when trying to get an key manager instance using SunX509 which is not supported.
> Currently KeyManager algorithm name  (SunX509) is hardcoded in the class X509Util.java.
> Possible fix: Instead of having algorithm name hardcoded to SunX509 we can fall back to the default algorithm supported by the underlying jre.
> Instead of having this -
> KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
> TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
> can we have ?
> KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
> TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
