When I click certain records in the log viewer of a Glassfish 2 server running on 64-bit Ubuntu the error report opens a new popup but instead of the actual error I get a server exception:

HTTP Status 500 -

type Exception report

message

Google came up with these two questions but with no real solution: 1. http://www.java.net/node/703568 2. http://www.java.net/node/682666

Does anybody have the same error or know the solution?
