If JSONRecord generates a runtime AbstractMethodError, compiling it with the same classpath would generate a compiler error. Do you know what that test.Settings... line is referring to? If not look up the line mentioned. Something about that reference is different between compile time and runtime.

I clean compiled each Scala library that touches the project (including lift), and made sure that their are no conflicting versions of Scala in the path (I checked with the Maven dependency plugin, and I do not get the warning that multiple versions were detected) but I am still seeing the error. Anything else I should try in order to eliminate library/compile versions as the culprit?
