plugin error := Exception in DataReceivedHandler

[gregy]

im reiciving a periodic error in log file - after the "keep alive" action.
the plugin appears to continue to operate and the arduino output control continues to operate as expected .. so doesnt appear "fatal"

HS3 Pro Edition 3.0.0.548 (Windows)
arduino plugin V1.0.0.166.
Sketch Version = 1.0.0.166, API Version = API1.0.0.146

edit : FYI. this is of course when using arduino connected via USB (com)
I have subsequently also programmed 2 other arduino for IP connectivity (using 5100 sheild)
& they do NOT exhibit this error . (i assume because IP doesnt use a keep alive style message)

sample log entries below (it occurs immediate after each "alive" message

also - not sure if its connected with above.

when compiling I recieve the below warning message from the IDE
(fresh install of arduino IDE V1.8.9 - as per the plugin page; correct version of libraries loaded from plugin page)
