Thread:Talk:ScalarR/ScalarR not stopping

Hi, I observe the following in the output of the rumble client

Fighting battle 44 ... aaa.r.ScalarR 0.005h.053,jk.mega.DrussGT 3.1.7
Robot aaa.r.ScalarR 0.005h.053 (1) is not stopping.  Forcing a stop.
Robot aaa.r.ScalarR 0.005h.053 (1) is not stopping.  Forcing a stop.
Unable to stop thread: aaa.r.ScalarR 0.005h.053 (1)
Unable to stop thread: aaa.r.ScalarR 0.005h.053 (1)

and the client seems to be running this battle with 100% CPU for at least several minutes (about 5). Then roborumble continued.

I am not sure where to search for the problem but there is something strange going on. I am running everything with

openjdk version "11.0.16" 2022-07-19
OpenJDK Runtime Environment (build 11.0.16+8-post-Debian-1deb11u1)
