In running FindBugs on our project, it fusses about having mutable servlet fields [1]. These fields are server @Reference fields that are managed by OSGi and don't carry any state. Should we be concerned about this "bug" from FindBugs?
Another suggestion made by FindBugs is to mark these fields as 'transient'. Is this common practice for service references in a servlet? Thanks, Carl 1 http://findbugs.sourceforge.net/bugDescriptions.html#MSF_MUTABLE_SERVLET_FIELD
