It sounds the same as this bug report:
http://jira.codehaus.org/browse/GMOD-95
If you're willing to build from source, try the RC-1 tag with the
replacement HTTPBuilder.java that's attached to the bug report. This
is something difficult for me to test myself, as I don't know of a
public web service that emulates the behavior.
But the NPE is thrown from w/in a catch block, which means it's
masking some other error that's occurring during parsing. If you can
try out that patch, please let me know your result.
