Build Identifier: M20100909-0800 In the following code: ------------------------------------------------ public class NullBinding { enum MyEnum implements java.lang.Comparable<MyEnum>, One< Outer<Integer>.Inner<Double>[]> { RED, GREEN, BLUE; } } interface One<Season> { } class Outer<T> { public class Inner<S> { } } ------------------------------------------------ eclipse creates a null binding for the ParameterizedType node Outer<Integer> that qualifies the array parameter of One Interface (3rd line of the code above). This shouldn't be happening. This also happens in eclipse 3.4. Reproducible: Always Steps to Reproduce: 1. Create a project with a file NullBinding.java and paste the code in the "Details" It's easier to see this bug in eclipse 3.4, using the ASTViewer plug-in.
The TYPE property of the ParameterizedType node also generates a null binding.
This works fine with HEAD. I am only getting a problem to create an array type.
Here is the exception I am getting. java.lang.IllegalArgumentException at org.eclipse.jdt.core.Signature.getTypeSignatureKind(Signature.java:1140) at

(In reply to comment #2) > This works fine with HEAD. I am only getting a problem to create an array type. May I ask you how are you testing whether the parameterized binding is null?
Closing as a dup of bug 333360. This is the same issue. Fixing one will fix the other one. I still need to investigate the problem found in comment 3. *** This bug has been marked as a duplicate of bug 333360 ***
