jdk-20+14-879-tier4 includes the following fix:
JDK-8173605 Remove support for source and target 1.7 option in javac
so I'm wondering if that fix includes a change in obsoletion
status for the source and target 1.8 option.
I'm starting this bug at priority P2 since this appears to
be a regression due to JDK-8173605.
