Both implementations of IBM JDK 5.0 and 6.0 have passed the JCK (Java Compliance Kit). This means that they both meet the spec for a 5.0 Java Virtual Machine implementation and their class libraries. This is not to say there may be behavioral difference between the 2 implementations in areas not fully covered by the JCK or in places where the spec is vague and open to interpretation.
This is my question.
Is there a known list of items that describe behavioral differences between IBM JDK 5.0 and 6.0 caused by vagueness in JCK?
