GreenHopper on EACJ produces a weird log messages - Needs investigation

Taken from EACJ logs

2009-09-17 23:38:29,644 main WARN [jira.issue.managers.DefaultCustomFieldManager] Custom field searcher module: com.pyxis.greenhopper.jira:exactnumber-gh is invalid. Null being returned.

GreenHopper : com.pyxis.greenhopper.jira
Version : 4.0-SNAPSHOT-jira40
Status : enabled
Vendor : Atlassian
Description : Rich Management Client for JIRA

ps looks like GreenHopper does not report its right version. The jar on eacj is

jira-greenhopper-plugin-4.0-beta6-jira40-complete.jar

but its internally reporting itself pretty badly.
