Given a Java annotation like this:

public @interface Foo {
    String bar() default "";
}

When used in Groovy on a method:

class Bar {
     @Foo
     def myMethod() {}
}

The value of the "bar" attribute does not take into account the default value of a blank string and instead returns null when used via reflection. Hence Java code like this will throw an exception:

String foo = ann.bar().length() == 0 ? null : ann.bar();

As the Groovy annotated method returns null. The workaround is to do this:

class Bar {
     @Foo(bar="")
     def myMethod() {}
}

But that is nasty
