Alternatively, you can use Choppy's (Disclaimer: I am the author) TryClose monad do this in a for-comprehension in a composeable manner similar to Scala's Try.

val ds = new JdbcDataSource()
val output = for {
  conn  <- TryClose(ds.getConnection())
  ps    <- TryClose(conn.prepareStatement("select * from MyTable"))
  rs    <- TryClose.wrap(ps.executeQuery())
} yield wrap(extractResult(rs))

Here's how you would do it with your stream:

val output = for {
  stream  <- TryClose(Files.lines(Paths.get("somefile.txt")))
} yield wrap(stream.findAny())
