Required version not working right

When trying to load a compiled version of RESTWS, get message "Error while trying to start module. Module requires version between 1.8.4 and , Current code version is 1.8.4.28691."

(Note rafa did not get this message, but his footer says "Version: 1.8.4-SNAPSHOT Build ${revisionNumber}" while mine says "Version: 1.8.4-SNAPSHOT Build 28691". My 1.8.4 is a little newer than his.)

Tried changing <require_version>${openMRSVersion}</require_version> to <require_version>${openMRSVersion}.*</require_version>. Got message "Module requires version between 1.8.4.0 and 1.8.4.999, Current code version is 1.8.4.28691".

Bug is that 1.8.4.28691 is not accepted as being >= 1.8.4.

Rafa suggests that <require_version> should be hard-coded rather than rely on the variable.
