Bug: JEXL writer.println prints blank line in output after intended line

[SwisscomHopperDevs]

Expecting that writer.println() prints its contents followed by newline. In output however it prints the line and then an extra blank line.

Also, expect writer.print() to not add a newline but it does.

Good catch. Let’s buffer output when print is called and remove the extra blank line.
