Topspin 4.5.0 on Alma 9

I've been running into a big in ICON where the Edit Parameter buttons stop
working during days of heavy use. Sort of seems like a memory leak, but I
wonder if upgrading Java might help. I can keep a handle on it by Logging out
of Alma and restarting Topspin/Icon on a daily basis. Tedious with 6 NMRs
and weekends.

Does anyone know the suggested version of Java to use for ICON/Topspin? I think
my Alma 9 instruments are all using OpenJDK v.17 but there is a v.21 out there.

Has anyone else run into this bug?

Thanks
