snapper x beast w/ java issue

[leonardslog]

Hello,

I'm attempting to run snapper in both beast 2.5 and 2.6.1 (installs w/ java) and am encountering the same error that looks like a failure to recognize the beast.core.parameter object (disclosure: not well versed in java). I manually installed snapper and similar to an issue in the google beast-users group, I wasn't able to load an alignment, so I tried simply running the simulation test xml file. It seems to start fine but cuts out early with the following message pasted below (from a linux attempt). Any idea what's happening? I tried this in both Windows and Linux, and figured I'd ask before trying implementation with BEAST installs using my native JRE. Thanks!
