-----------------------------------------------
[~valenpo] Valentin, realistically there is nothing we can do about it. I'll
see if somehow repetitive calls to {{JsseJce#getKeyGenerator}} could be avoided
but I am afraid you are entirely at Oracle's mercy here.

> Hi,
> We meet this problem in our application. We are using different libs depends
> from httpclient: azure, jclouds, backblaze, etc, encryption for files we
> archiving. It is used everywhere. And after 3 days of usage application stack
> on getService().
> I have a [JFR
> Snapshot|https://www.dropbox.com/s/cpgx406vkqpvc80/2018-06-25_08-11-23.jfr.zip?dl=0]
> in such condition. If you go to Contention in JFR snapshot you will see
> java.security.Provider.getService() is a bottleneck for application.
> It is already opened [bug|https://bugs.java.com/view_bug.do?bug_id=7092821]
> in Oracle database, but I'm not sure it will be fixed any time.

> Most of stack traces start from
> {code:java}
> Stack Trace Count Duration
> sun.security.ssl.SSLSocketImpl.startHandshake() 1,055 4,767,153,771,586
>
> org.apache.http.conn.ssl.SSLConnectionSocketFactory.createLayeredSocket(Socket,
> String, int, HttpContext) 792 3,716,363,189,042{code}
> Is it possible somehow share Socket, so we don't need handshake each time.
