This doesn't really tell me what the error is.
Did you set the compliance, source and target platform to be 1.7.

You need to make sure that the type annotation NonNull is on the 
classpath.

JDT/Core doesn't provide such annotations. They must come from the 
libraries on the classpath.

You can check the two test classes:
/org.eclipse.jdt.core.tests.compiler/src/org/eclipse/jdt/core/tests/compiler/regression/NegativeTypeAnnotationTest.java
/org.eclipse.jdt.core.tests.compiler/src/org/eclipse/jdt/core/tests/compiler/regression/TestAll.java

You need to grab them from the JSR_308 branch.
They contain lots of examples of the syntax accepted by the compiler.

It would probably be a good idea to continue this thread either on the jdt 
newsgroup or directly through emails.
This is not the kind of discussion that feets well on the eclipse-dev 
mailing list.

Let me know if you have other questions.
