How to create a "NonBlockingConnectionPool "using a "java.sql.Connection" object already present ?

[ArijitCode]

I tried creating a connectionpool using rxjava2-jdbc using a java.sql.Connection Object .

NonBlockingConnectionPool pool =
Pools.nonBlocking()
.maxPoolSize(Runtime.getRuntime().availableProcessors() * 5)
.connectionProvider(ConnectionProvider.from(connection))
.build();
But it strangely throws this NoSuchMethodError exception :

Caused by: java.lang.NoSuchMethodError: com.github.davidmoten.guavamini.Preconditions.checkNotNull(Ljava/lang/Object;Ljava/lang/String;)Ljava/lang/Object

Scenario :-
I already have a java.sql.Connection Object , How to I use that to create a org.davidmoten.rx.jdbc.Database Object so that I can execute my SQL queries from ?

Ah, there was a breaking change in guava-mini, check you have latest version of rxjava-jdbc and other libs. If there is a mismatch I'll fix with another release.

Can you please help me with some sample code doing specifically the above ?
