It looks like there is a hiccup in the Skara mlbridge bot. I added the following PR comment this morning:

https://github.com/openjdk/jdk/pull/3407#issuecomment-817771898

It was sent twice to the mailing list about 5 hours apart:

https://mail.openjdk.java.net/pipermail/awt-dev/2021-April/017469.html
https://mail.openjdk.java.net/pipermail/awt-dev/2021-April/017474.html

Even more puzzling is that the following two long-running PRs in jfx were partially replayed this morning. Many of messages in question were more than 1 year old.
