I came across a strange problem after using NG Client, it is observed that 3 headless clients are launched successfully and as soon as we launch 4th headless client following error is logged related to NG Client (my NG Client UUID was 78657EB8-877C-4594-BEB4-F4B3C799FFEC) .
ERROR ClientManager - Error flushing message buffer to client 78657EB8-877C-4594-BEB4-F4B3C799FFEC java.lang.IllegalArgumentException: null
