[Bug] Always thrown `StreamingQueryException: No client available` when shaded jar is assembled with spark 2.4.5 (JDK1.8)

[oliverdding]

I'm testing clickhouse-jdbc with Spark 2.4.5, but org.apache.spark.sql.streaming.StreamingQueryException: No client available is always thrown.

I swear that I added the classifier "all" like this(sbt):

"com.clickhouse" % "clickhouse-jdbc" % "0.4.0" classifier "all"

After jar -xf the assembled jar file, I could find the http client related class file:

---

Then I looked into the source code of clickhouse-http-client, and found this:

    CONNECTION_PROVIDER("http_connection_provider", HttpConnectionProvider.HTTP_URL_CONNECTION,
            "HTTP connection provider. HTTP_CLIENT is only supported in JDK 11 or above."),

I'm not sure if this is related, so I'm asking for help. Thanks for any advice.
