Nick Allen updated METRON-1916:
-------------------------------
Description:
Stellar can be executed in an environment where not all of the dependencies are
available for each of the functions provided in Stellar Common. When this
happens, the classpath resolver blows-up even if you do not use the function
that is missing dependencies.
For example this exception is thrown when not all of the dependencies are
available for the new REST function. I was only attempting to use STATS_INIT,
not the REST function.
