public ApnsServerSocketBuilder withSSLContext(SSLContext sslContext) {
		this.sslContext = sslContext;
		return this;
	}
Specify the SSLContext that should be used to initiate the connection to

Most clients would use {@link #withCert(InputStream, String)} or
{@link #withCert(String, String)} instead. But some clients may need to
represent the Keystore in a different format than supported.

@param sslContext
