Thread: [Bodington-developers] Possible bug in Java 1.5.0

I've come across what might be a bug in Java 1.5.0

It first showed up when I upgraded our system to 1.5.0 and file uploads
stopped working with mvnForum behind a Guanxi guard.  They worked fine if
mvnForum was not behind the guard.  At first I thought this was a problem
with Guanxi and contacted Alistair, but I now know the problem actually lies
in Java (humble apologies and cakes to Alistair).

When an mvnForum user tried to upload a file, he/she was presented with a
null pointer exception. This was generated in mvnForum (actually in
net.myvietnam.mvncore.fileupload.FileUpload) at the following code:

HttpServletRequest req;
public static final String CONTENT_TYPE = "Content-type";
String contentType = req.getHeader(CONTENT_TYPE);

I put a bit of debugging code into the mvnforum and guanxi code and was able
to show that the 'content-type' header was arriving at the guard OK and was
being  passed through to the mvnForum class when the guard rewrote the
request.  According to the Java docs, the string passed to
request.getHeader() is case insensitive.  However, the exception went away
when I changed the code to read:

public static final String CONTENT_TYPE = "content-type";

Seems the definition of case-insensitive isn't quite what you might expect.
