As it happens, ThreadInfo is only used in xhtml as a class to hold row data (from treeThreadBean.allThreads where treeThreadBean is a legitimate managed bean. Hence I don't believe I'll need to create a managed bean for ThreadInfo, I can simply remove it from faces-config.xml. From my brief look into the faces-config.xml file it appears that a number of classes have been defined in there as managed beans that shouldn't have been (eg ThreadInfo, Snapshot, FrameInfo, AllocationInfo and others, none of which are referenced anywhere in the .xhtml as managed beans). I'll investigate each one and remove as necessary. If a bean is needed, I'll abstract one into the .web package as discussed.
