I've confirmed that the JVRC1 robot can walk in lipm_walking_controller in Choreonoid with this patch.
However, there is no explicit confirmation that this fixes the bug https://github.com/jrl-umi3218/mc_rtc/issues/289 effectively. (It is also not clear how to identify bugs from the robot's behavior and logs in the first place.)
This should fix https://github.com/jrl-umi3218/mc_rtc/issues/289
