Coverage decreased (-0.03%) to 56.787% when pulling e9ddcc5 on danielb987:JmriException_multiline into 50e8b2b on JMRI:master.

[danielb987]

@bobjacobsen Do you want all the exceptions that inherits JmriException to also have the constructors that takes the list or can that wait until somebody wants it?

[bobjacobsen]

I think it's fine to wait on that.
