Comments
The only indication of problem are AOT compilation failures I observed and posted in Slack. I don't think it is urgent.

Yes, this is the problem discussed in Slack, and I already started working on it. I don't think Igor's suggestion is enough. Is this currently causing any CI or nightly failures? If so, we can look into doing a quick fix that disables invokedynamic support.

[~dlong] Will you look on this or you want me to look? You know more about invokedynamic support. Also, please, add command line to reproduce the failure. Should we use this bug to fix problem discussed in Slack channel and use Igor's suggestions?
