[26/3/2001] java.io.InvalidClassException: org.netbeans.modules.java.JavaDataObject$PersistentConnectionHandle; Local class not compatible: stream classdesc serialVersionUID=6508687471667673911 local class serialVersionUID=-5037573245209142090
If it only pollutes the console/log, it's OK; the old (buggy BTW) version is not compatible. JavaConnections support will relink itself as you continue to work on your sources. if it shows up in an exception dialog, it is a problem.
No dialog is shown :-).
Won't fix this one - the code synchronization has to migrate over time to the new serialization format.
Resolved for 3.3.x or earlier, no new info since then -> closing.
