The "provides" value has changed in java-1.8.0-openjdk-headless.x86_64,
version 1:1.8.0.392.b08-2.el7_9, rpm.

Previous versions of this package listed "java-headless = 1:1.8.0", and
u392 has a specific minor version tied to it: "java-headless =
1:1.8.0.392.b08-2.el7_9".

The result is that third-party packages that require specifically
"java-headless 1:1.8.0" are not compatible with the new version 392.
