That's simply the nature of the underlying operating system constructs that Java streams represent. A stream is essentially a data conduit. Once you close it, it no longer exists. You may be able to create a new one between the same endpoints, but that yields a fundamentally different stream. The connection pool attribute to set is abandoned-connection-timeout, which is in secs, not minutes. In the exmaple config is set to 60, which is why the connection is getting reclaimed by the cache.

Creating connection is an expensive operation so it's not best practice to open and close connection frequently.
