From Jmri
[edit] Tons of errors on stratup of 1.7.2
It turns out that, at least on my installation, the 'jmri.jar' file that comes with the package was toast. Fortunately, I had a replacement (thanks, Paul!) that did the trick. Hopefully, Paul will make this available as it also fixes the broken-throttle-slider-in-1.7.2 issue as well. - Please update!
