The OpenJDK 7 recently introduced the UNUSED() macro in their jni_md.h header file, which is included from <jni.h>. This causes a compile-error if "constants.h", which defines our own UNUSED() macro, is included as well as <jni.h>. The OpenJDK UNUSED() macro is unsuitable for our own use, because it prefixes the unused identifier with "UNUSED_" whereas we depend on the parameter name remaining unchanged. I have reported this as a Request for Enhancement with Oracle Java, asking them to remove the UNUSED() macro, since it is not used by any JNI or Java extension header files. Review ID: JI-9013689. In the meantime, constants.h now undefines UNUSED before defining it, so including <jni.h> before "constants.h" will avoid a compile error.
