AWS core has "SunX509" as a hard-coded Key Manager option.

Describe the bug

Using the API on IBM JRE where:
ssl.KeyManagerFactory.algorithm=IbmX509
will fail to create Key Manager.

Expected Behavior

choosing the default key manger would let users use other options, for example ibmX509.

Current Behavior

Using the API on IBM JRE where:
ssl.KeyManagerFactory.algorithm=IbmX509
will fail to create Key Manager.

Steps to Reproduce

Possible Solution

KeyManagerFactory KMF = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
should fix this.

Context

I am trying to use the AWS API, running on IBM JRE. getting errors when SunX509 is not found.
