I didn't say this. I was just making the point that in the future that 
using system calls and native code will be a lot better (simpler, more 
reliable, faster, ...).

Thanks, that is the right place to discuss this issue.

If MultiParentClassLoader defines a method to get its parents then you 
can walk the hierarchy, special case MultiParentClassLoader, and calling 
getDefinedPackages on each one. It's not going to help if there are 
other custom multi-parent loaders from elsewhere in the hierarchy but I 
can't tell if this is possible here.
