[OSM-dev] Problem installing Osmosis on OSX

[Brett Henderson]

That's very strange.  I compile it with jdk1.6 and it appears you're 
running 1.6 so I don't understand what is happening.  The 
UnsupportedClassVersionError usually only occurs if you try to run 
osmosis with an old version of java.

Perhaps try getting the java command line out of the osmosis launch 
script and run java directly from the command line.  Perhaps my launch 
script is doing something funky and running the wrong version of java ...

Does anybody else have any ideas?
