Is BCEL working with Java 1.5? Metrics tools?

Hello, 

I am trying to develop some code metrics tool using BCEL, 
so I have a couple simple question about BCEL. 

1) Is BCEL working with Java 1.5 properly? What about new 
   code structures in Java 1.5? 
   I have tested BCEL for some simple code with new syntax in Java 1.5, 
   but I am not sure that BCEL will work fine for all new syntax. 

2) Did you try to write code metrics tool using BCEL?
   I would like to count some simple metrics and CK code metrics. 
   That would be great if you have any comments about that. 

   I have also tried Metrics tool (metrics.sf.net) which is a very good 
   tool, but it has to work in Eclipse IDE (as a plugin). I am searching 
   for good metric tool that could be run without Eclipse, especialy 
   using Ant tool. 

I am gratfull for any help from you. Please, feel free to write to me. 

Best regards,
Peter
