[aspectj-dev] NPE with @args

[Oliver Böhm <boehm@xxxxxxxxxx>]

Hello,

I defined a @NotNull annotation to protect in the first step 
constructors like this:

    public NotNullTest(@NotNull String s) {
        ...
    }

I defined the following pointcut and (empty) advice:

    pointcut ctorWithNotNullArg() :
        execution(*..*.new(*)) && @args(NotNull);

    before() : ctorWithNotNullArg() {
        // empty
    }

When I call the NotNullTest constructor with a null string I get a 
NullPointerException pointing direct to the first line of the constructor:

java.lang.NullPointerException
    at patterntesting.check.runtime.NotNullTest.<init>(NotNullTest.java:48)
    at 
patterntesting.check.runtime.NotNullTest.testCtorNotNullArg(NotNullTest.java:76)
    ...

I don't understand why I got a NPE here. When I use "args(String)" 
instead of "@args(NotNull)" it works normal. Is this behaviour a known 
bug or did I something wrong?

regards
Oliver
