Bryce pointed out that there is another solution that he favours,
which involves gdb reading libgcj's metadata.
There is already (somewhat bit-rotted) code to do this - but of
course for the old ABI.
Note that we need a solution that also handles dynamically-loaded
interpreted or (future) jit-compiled classes.
That argues for having gdb reading meta-data from the interior.
Both solutions require gdb changes: to generate DWARF data at runtime
requires some changes because gdb is used to reading debug data from
object files, not from the inferior process.
The Java support in gdb can sort-of do either.
