Seems like a good idea. I'll try to find a moment to test this. What are the benefits we get from this upgrade? Performance? Footprint? In case it helps anyone else, the JIRA with these attachments is: https://issues.apache.org/jira/browse/HARMONY-6096 (I don't think there is an easy way to get from attachment links back to the jira link?) Regards, -Mark.
