I got similar problem but my exception is "java.security.AccessControlException: access denied (java.util.PropertyPermission SERIALIZATION read)." I don't use Java Security Manager. What does this "SERIALIZATION read" mean? Why do I get the AccessControlException even I don't use java.security.manager commandline option? Thanks in advance!
