Is there any maintenance being done on Metro? I submitted 2 bug tickets over the last 1.5 years and haven't gotten any kind of response.
https://java.net/jira/browse/METRO-30 is the most important one as it greatly reduces the use of debugging.
https://java.net/jira/browse/METRO-21 is another that has been around for a long time but is pretty minor.
If no maintenance is done anymore we'll have to switch to another library but other than these 2 things I like working with Metro so I hope this is not necessary.
