TreeMultimap has serialization issue

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create TreeMultimap using create(keyComparator, valueComparator) method
2. Provide comparator classes which are not declared serializable.
3. The class gets instantiated without any problem.

What is the expected output? What do you see instead?

- When trying to serialize the class, you get NotSerializableException error

What version of the product are you using? On what operating system?

Guava-r08 on JDK 1.6 for Mac OS X

Please provide any additional information below.

All serializable objects that make use of user-provided objects (including 
collection elements, comparators, or whatever) are not serializable if any of 
the user-provided objects they contain are not serializable. The same thing 
would happen with TreeMap, for example.
