FindBugs
I ran FindBugs on AppFuse last night and found/fixed a number of issues as a result. I'm now down to only a handful left - most of them being "Class is Serializable, but doesn't define serialVersionUID". I tried to generate one using serialver, but I couldn't it to work after numerous attempts. My issues seemed to be classpath related: it wanted the servlet api in my classpath, and once I'd add that, it could find my class. I'll have to try the SerialVer Ant Tasks. Fixing this issue would be nice, but I doubt it's really affecting appfuse-based applications. The other bug is "Inconsistent synchronization" in UserCounterListener.contextInitialized() method. Any tips on solving this one are appreciated.
