In my projects I usually just use the `ConstantBootstraps` method directly, which avoids the try/catch (but does not avoid needing a lookup). In my mind I imagine eventually writing a tool which post-processes my classes and replaces all `private static final Xxx xxx = ConstantBootstraps.xxx()` with dynamic constants (similarly, I guess, to what @liach suggested). But maybe just using the existing `ConstantBootstraps` methods is a good stepping stone towards a JEP-303 kind of solution.
