Hello, I'm trying to write a solr driver for metabase. Internally metabase uses a C3P0 connection pool. Upon checkout of the connection from the pool the library does a call to isValid(0) (timeout = 0)
According to the javadocs ( https://docs.oracle.com/en/java/javase/11/docs/api/java.sql/java/sql/Connection.html#isValid(int)) a timeout = 0 means no timeout. In the current implementation a timeout = 0 means that the connection is always invalid. I can provide a PR for this.
