Redefinition of m_mask in TaskJointPosture

[jacqueszhong]

Hello,
There is a small issue in TaskJointPosture.hpp (so I'm not sure this is worth a Pull request).
With the redefinition of m_mask in TaskJointPosture.hpp, getMask() does not work properly for me and prints the m_mask of the parent class TaskMotion (where m_mask is not initialized).

Best regards,

Well spotted! It's weird that this is tolerated by the compiler. I'm gonna fix it right away
