How does one go about it? I'm not on any lists or part of the project.

Perhaps someone could save me some time and review the code first, to 
see if it's suitable?

Yes turns out RFC 3986 is very useful.  Our implementation is strictly 
compliant, with the exception of making upper case path comparisons for 
file URI's on certain platforms, it's based on Harmony's URI, but has 
been refactored with immutability; final class, final fields, isn't 
serializable etc.  The parser is called during construction using static 
methods.  Exceptions thrown by constructors are thrown by static methods 
prior to Object's default constructor being called, to avoid creating 
partially constructed objects.

These considerations were important for security.
