Solrj 9.3.0 integration with AEM 6.5, Http2SolrClient issue

[acgurnani]

Hi,

I'm looking to integrate AEM 6.5 with Solrj latest version (9.3.0).

I see everywhere the SolrClient used is via HttpSolrClient but as per latest 9.X updates , it has been deprecated and Http2SolrClient is being suggested, but I cant find any examples to use the same .. 

If I try using the Http2SolrClient , I'm facing the below error when I'm building the same

Code : 

new Http2SolrClient.Builder(solrUrl)
        .withConnectionTimeout(9000, TimeUnit.MILLISECONDS)
        .withIdleTimeout(9000, TimeUnit.MILLISECONDS)
        .build();

Error :

As per the document shared, they are also using the old client :

private static HttpSolrClient getClient() {

        return new HttpSolrClient.Builder().withBaseSolrUrl("http://localhost:8983/solr")
                                           .build();
    }

which has been deprecated as per Solrj 9.0.0 - https://solr.apache.org/docs/9_0_0/solrj/deprecated-list.html

I want to connect using the new Http2SolrClient as per the latest standard.

Hello @kautuk_sahni 

I still have no solution for the above, even reducing to 8.X version of Solr I wasn't able to find the solution.
