SslContextUtils methods fail when the indicated KeyStore contains PrivateKeyEntry objects

[criege]

I haven't tested this extensively yet but in a nutshell, lets assume there is a KeyStore holding two entries, one of type PrivateKeyEntry and the other of trustedCertEntry. Additionally the store is protected by a password.

Retrieving the KeyStore by calling one of the methods on KeyStoreLoader that takes a password everything works as expected.

However once trying to call SslContextUtils.buildMergedWithSystem(KeyStore) the method fails due to a missing password – namely the password of the PrivateKeyEntry (which happens to be different from the store password). Here's the stack:

I've fixed this locally by not using CompositeX509KeyManager but just the default system key manager. But I'm not sure if this is to your intention :). If you want I'll make a PR …

Thanks for the feedback. :)

Just to clarify: Your code falls back to the default system key manager specifically when the passphrase is missing?
Sure, a pull request would be great. Perhaps I could later add an overload for buildMergedWithSystem() that takes a passphrase.
