In what cases do we not have a method index? In general the index for an
interface method should not be -1. see:
_Jv_Linker::layout_interface_methods(). It sounds like a bug if you are
seeing -1 values at runtime.
Presumably, the bug being seen here is gcc.gnu.org/PR15001 ? This is a
serious regression that must be fixed for 4.0, even if the fix results
in a (temporary) performance regression, eg: disabling fast interface
dispatch for reflection. We'll have to come up with something better for
