This is a long-standing tomcat problem that is mentioned from time to time on the tomcat list. The problem arises because recompile gens a new class serial id which confuses tomcat. The last I heard, the tomcat folks dismiss it as a classloader problem and suggest that you do what you did: restart tomcat.
