If this is at NB startup…Not sure if this has changed in newer NB versions but in the Netbean folders etc/netbeans.conf the default netbeans_jdkhome in use property points to default jdk version that NB runs on. (1). It’s also possible to specify the location from command line when starting NB.
Believe this is the version NB is running on (which should at minimum be compatible with version that NB was built with). Not to be confused with the Project Java property in use or the available installed Java Platforms. As I recall, Java 8 was the last non-openjdk release by Oracle after which the release process and cadence change with emphasis on openjdk (open source based). Oracle still offers security updates (especially if there is a support contract) but many of the older versions are reaching End Of Life (EOL). Java 8 I believe is the last version with Java with update monitoring; I believe this was removed or not actively supported in the openjdk version.
