I understand your concern. The reason I am actually copying the JTable contents is partially to mitigate the risk of blocking for too long the EDT or using the JTable accidentally outside of it and also to decouple the core export code from Swing. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
