[JSR308] ClassNotFoundException using BasicChecker

[Jonathan Gibbons]

Mahmood,

You should be able to use the -processorpath option for javac to load  
the annotation processor classes.

The use of the CLASSPATH environment variable is somewhat antiquated  
-- you should be able to do everything through command line options.
