Subject says it all. Our second CHF for ColdFusion 9.0.1 has been released. You can find details here:

http://kb2.adobe.com/cps/918/cpsid_91836.html

Some good fixes here, including:

• ColdFusion does not resolve the CFC's fully qualified name correctly when a relative path is used in the application mapping.
• ColdFusion throws "java.lang.IllegalStateException: Session is invalid" exception randomly.
• serializeJSON converts integer to string.
• serializeJSON incorrectly serializes nested objects. Also, in the case of circular references, for example, when handling bidirectional ORM relationship, repeating entities are represented as empty strings instead of empty objects. </ul>
