Archiving Admin Console Menu option fails to appear if indexprops.xml is corrupted

[staples1347]

In version 2.2.1 of the monitoring plugin and possibly newer version if the server crashes , the indexprops.xml files will often reset to 0 byte size and then when the Openfire is restarted, the monitoring plugin will continue to archive messages, but fail to add the Archiving menu option to the admin console. I haven't checked if the menu still fails to appear in the latest version of monitoring , but it looks like the latest version of the loadPropertiesFile function in LuceneIndex.java still doesn't check if XMLProperties has failed.

I think it should check if XMLProperties has failed and possibly recreate the XML file if this is the case as the valid version of the file only contains a lastModified tag.

Here is an example crash log if indexprops.xml is 0 bytes:
