Hi GF fans,
I'm developing a REST endpoint that accepts file uploads and I used a
bunch of System.out statements to see what I can get from certain
objects. If any method returns null, GF throws a NPE. That NPE gets
thrown by the logging mechanism and I think that is a bug; there should
be a null check within the logging framework, shouldn't it? Otherwise
it'd be a bit confusing and it adds overhead, because the coder has to
add NP checks around their test output:
if (bodyPart.getContentDisposition().getModificationDate() != null) {
System.out.println(bodyPart.getContentDisposition().getModificationDate());
}
That's the exception:
