Ok, I have resolved this issue. Problem was in used security provider "org.openjsse.net.ssl.OpenJSSE" (I don't know if this is default)

So I removed this security provider programmatically from providers list

Security.removeProvider("OpenJSSE");

Then next valid security provider was used for https.
