seemingly spurious WARNING: Connection listener error Exception: null

[thirschbuechler]

Hi,
I run the script with openjdk11 and get a seemingly spurious "WARNING: Connection listener error Exception: null" now and then
(~2-4 errors per 16 captures a run, aquisition time ~3-6s)

Is there any significance to it? Data output seems fine

Shouldn't be happening. If data output is fine, that's a good sign, however we do need to investigate and make sure it's fixed.
