This was fixed in Jersey 1.0.1, see:
https://jersey.dev.java.net/source/browse/*checkout*/jersey/trunk/jersey/changes.txt
- Fixed issue 128
https://jersey.dev.java.net/issues/show_bug.cgi?id=128
An method parameter that is a request entity is a parameter that is:
1) not annotated with any annotations; or
2) annotated with one or more annotations all of which are
recognized by
the Jersey runtime.
