/**
 * Implementation independent test for HttpsURLConnection.
 * The test needs certstore file placed in system classpath
 * and named as "key_store." + the type of the
 * default KeyStore installed in the system in lower case.
 * <br>
 * For example: if default KeyStore type in the system is BKS
 * (i.e. java.security file sets up the property keystore.type=BKS),
 * thus classpath should point to the directory with "key_store.bks"
 * file.
 * <br>
 * This certstore file should contain self-signed certificate
 * generated by keytool utility in a usual way.
 * <br>
 * The password to the certstore should be "password" (without quotes).
