8  * Polyglot type information, but is unable to read in the serialized class
9  * information. The most likely cause of this exception is that the compiler
10  * (or compiler extension) has been modified since the class file was created,
11  * resulting in incompatible serializations. The solution is to delete the class
12  * file, and recompile it from the source.
