RFR: 8255014: Record Classes javax.lang.model changes, follow-up

[Vicente Romero]

Hi,

I made the mistake of pushing the fix for [JDK-8253455](https://bugs.openjdk.java.net/browse/JDK-8253455) too soon and
had to delta-apply it. This PR is basically proposing to push the same code as
[PR-291](https://github.com/openjdk/jdk/pull/291),

Thanks and sorry for the unnecessary loop,
Vicente
