Many warning messages are generated when compiling JConsole with -Xlint:all. These are mostly of type deprecation, unchecked, and serial. A clean build is desirable.
There are 41 classes affected by warning messages.
Of these, 28 only report a missing SerialVersionUID when extending Swing classes. An annotation to suppress serial warnings will be added to the top-level classes.
The remaining 13 classes also need minor changes to remove warnings of type deprecation and unchecked.
