Eh? I am not sure what you mean here. This is the essence of the patch, where
the "TODO" above is fixed: lookup.findStaticVarHandle now creates lazy
varhandle if the defining class of the field is not initialized.
The fixing of IndirectVarHandle.isAccessModeSupported is a side effect, because
the override of `getMethodHandle` in `IndirectVarHandle` appears to me as a
no-op; turns out it exists due to NPE in isAccessModeSupported, which IMO
should be fixed as it's a public API.
