Looking at line of code, we get this wrong request:  
"delete from PERMISSIONS where PERMISSIONS.OBJECT_ID in (select ou.URI_ID from  
URI ou, URI su, URI au where ou.URI_STRING = ? and SUBJECT_ID = su.URI_ID and  
su.URI_STRING = ? and ACTION_ID = au.URI_ID and au.URI_STRING = ? and  
VERSION_NO" + ((revisionNumber == null) ? " IS NULL " : " = '" +  
revisionNumber.toString() + "'"  
  
where i think we should read this:  
"delete from PERMISSIONS where PERMISSIONS.OBJECT_ID in (select ou.URI_ID from  
URI ou, URI su, URI au where ou.URI_STRING = ? and SUBJECT_ID = su.URI_ID and  
su.URI_STRING = ? and ACTION_ID = au.URI_ID and au.URI_STRING = ? and  
VERSION_NO" + (((revisionNumber == null) ? " IS NULL " : " = '" +  
revisionNumber.toString() + "'")  +")"
