Check for Java 21 for OH5?

[mstormi]

Some maintainer asked if we could check for Java 21 to exist when switching to or installing snapshots (OH5 now which requires Java 21)

not sure what / how much we would need to do here.

We could probably just install the BelSoft 21 routine if needed.

[mstormi]

better to install OpenJDK 21, Belsoft was just for some special case not exactly sure but was'nt it 32bit?
read somewhere that Java 21 is backwards compatible such that if someone changes back to OH4 release they can keep java.

[ecdye]

I think BellSoft was for arm32 primarily but appears to work elsewhere.

I haven't really looked into it at all, but I do know that on bookworm the JDK 21 hasn't been added to the APT repo.
