[stevenfuhr]

Version

1.49.0

Steps to reproduce

Currently setPfxPath does not properly add client certificates.

Code snippet:

ClientCertificate clientCertificate = new ClientCertificate("https://localhost:8443");
clientCertificate.setPassphrase("passphrase");
clientCertificate.setPfxPath(Paths.get("/path/to/client_keystore.p12"));

List<ClientCertificate> clientCertificates = List.of(clientCertificate);

Browser.NewContextOptions options = new Browser.NewContextOptions();
options.setIgnoreHTTPSErrors(true);
options.setClientCertificates(clientCertificates);

context = browser.newContext(options);

Expected behavior

PKCS12 certificates are properly added to the context.

Actual behavior

The certificate is not be present in the context.
