SunX509 KeyManagerFactory not available - running IBM JVM

[ghost]

I have implemented the code for Composite-JKS as described for my java client. I used Maven to add the dependency and added the SslContextUtils.mergeWithSystem(getClass().getClassLoader().getResourceAsStream("trust.jks")); statement to my java client. When I execute this statement, I receive the following error:

I found similar issues for other projects which indicate that the problem is that the SunX509 KeyManagerFactory is not available on a system running the IBM JVM. The solution was to allow the algorithm to be configurable. (See https://code.google.com/archive/p/javapns/issues/39 and https://code.google.com/archive/p/javapns/issues/41)

Is this option already configurable for CompositeJKS or can you add this support?

Thanks for reporting this issue.

I have introduced a new static field SslContextUtils.X509Algorithm in commit 6e5314d. It defaults to SunX509 but can be overriden for use on other JVMs.

I will create a new release of CompositeJKS that includes this commit soon.
